Best Used Car Websites: Which Ones Are Actually Worth Using?

Buying a used car online is more accessible than ever, but that doesn't mean it's simple. One site might offer the widest selection, another might be best for price comparisons, and a third might make the purchase process easy. That is why the best used car website depends not on the tool but on the intention.

The best used car websites, compared

1. Autotrader: most useful for a broad search on the beaten path

Autotrader is a great place to start if you need a jumping-off point and aren't sure where to begin. It is one of the deepest and broadest used-car marketplaces in terms of both inventory and the number of participating dealers. Most importantly, it emphasizes one critical pillar of the used car buying process: the ability to browse a wide selection of vehicles.

The good stuff

• Autotrader is a Cox Automotive company: it aggregates inventory from both car dealers and private sellers.
• Includes Kelley Blue Book pricing data (another Cox Automotive brand).
• Excellent value across different brands, body styles, and price points.

When it shines

Starting your search here if you're looking to cast a wide net and find vehicles across different retailers.

2. Cars.com: best for inventory, research, and dealer discovery

While some shoppers focus on finding the best price, Cars.com has built an ecosystem to help shoppers compare used vehicles. Beyond inventory search, the site also offers research, comparisons, financing information, dealership discovery, and buyer-focused content.

What it offers

• Allows comparison between different vehicle classes simultaneously.
• Best for buyers who want to research what a particular deal at a given dealer means.
• Cars.com hosts around 16 million consumer reviews of dealerships and uses the data to determine its annual Dealer of the Year.

Limitations

• Listing quality varies by dealer. Some list vehicles with dozens of photos and a vehicle history report, while others only have a handful of photos and minimal information.
• Not all listings are the same, and it may be difficult to identify fair pricing without additional research.
• Should be used in conjunction with other price-comparison services to identify if a particular listing is a good deal.

Who it's best for

Buyers looking for a comprehensive overview of the used vehicle marketplace that can include research, price comparisons, and financing options, along with reviews of individual dealerships for their purchase.

3. Edmunds: best for research-first buyers

Edmunds has more value pre-purchase than at the point of sale, and its primary purpose is to educate buyers on what to purchase.

Disclosure: Edmunds has been a wholly owned subsidiary of CarMax since June 2021.

What makes it useful

• Vehicle reviews and comparisons.
• Pricing tools including Edmunds True Market Value, also known as Edmunds Suggested Price, plus its vehicle appraisal tools.
• Value in narrowing a broad search to 2-3 viable options.

Strongest use case

Edmunds has the most value when you’re asking yourself:

• Is this a good used car buy?
• Compared to what?
• Am I paying too much for the option, trim, mileage, or age?

Limitations

• Not a tool for a seamless, single-website purchase journey.
• Buyers seeking the broadest selection may favor marketplaces for inventory discovery.

Who should use it

People who want to avoid used-car purchase regret from an incomplete research process.

4. CarGurus: best for price-focused comparison shoppers

CarGurus is often cited as a go-to resource for comparing asking prices and doing due diligence to determine whether a price reflects fair market value.

Why do buyers use this site? 

• CarGurus has listings that have Deal Ratings such as Great, Good, Fair, High, and Overpriced.
• CarGurus bases Deal Ratings on Instant Market Value, which uses current and past listing data to determine what a vehicle should realistically cost.
• An excellent resource for comparison shopping, especially for those who are focused on value.

Best for

Comparison shoppers more concerned with a vehicle's value than its availability, which is typical for value shoppers.

Caveats

• Asking price is only one part of the due diligence a buyer must do when purchasing a used car from an online marketplace.
• A good Deal Rating does not indicate accident history, reconditioning quality, dealer fees, or other important criteria.
• As with most online marketplaces, the data is only as good as the sellers' input.

Who should use this tool?

Value shoppers who are willing to comparison shop based on asking prices are likely to find CarGurus to be the most useful of the tools reviewed in this article.

5. CarMax: best for a low-hassle buying process

CarMax is an unusual option because it isn't quite an open marketplace. Instead of facilitating deal-making between a broad range of interested parties, it acts as a large-scale used-car dealer.

What makes it useful

• CarMax provides a 10-day Money Back Guarantee.
• Most vehicles come with a 30-day limited warranty with no mileage limit and no deductible, and some states offer state-specific guarantees.
• CarMax uses a no-haggle policy and offers a transparent up-front price for most vehicles, so you know what to expect for the final price.
• The company has an expansive network of corporate retailers across the country.
• Additionally, it offers home delivery within a radius of certain locations.

Best for

Those who do not care about shopping around as much but want to ensure that they know what they are paying for and are not being taken advantage of in the process.

Limitations

• The fact that you only look at one seller's inventory means that you have fewer options at a given moment and may have a harder time finding a car within
• your price range.
• Some shoppers want the most competitive prices at any moment, which requires a more comprehensive approach.
• Convenience comes with a cost, and the overall value proposition depends on the availability of exceptional opportunities.

Who should use it

Customers who want to streamline the car-buying process as much as possible while still having access to in-store assistance if needed.

6. Carvana: best for online-first convenience

Carvana is one of the best options for buyers who want to avoid most in-person aspects of the car-buying process. CarMax, Amazon Autos, and many franchise dealers now offer online purchasing or delivery options, but Carvana is built around an online-focused buying process.

What it offers

• A 7-day money-back guarantee lets buyers return a vehicle after delivery, depending on Carvana's terms.
• A 100-day/4,189-mile limited warranty covers vehicles.
• Home delivery is an option, or buyers can opt for a vending-machine-style pickup at a Carvana kiosk, depending on location.

Best for

Convenience-focused shoppers looking to make as many aspects of their used car purchase online as possible.

Limitations

• You cannot inspect or test drive the car before completing the purchase. The 7-day return period effectively replaces the traditional pre-purchase test drive.
• The online process replaces the traditional dealer visit but does not eliminate the need to examine the vehicle thoroughly.
• Inventory and pricing still need to be viewed in the context of the broader used market.

Who should use it

Consumers with the ability and willingness to make a used car purchase almost entirely online.

If the vehicle you want is located far from home, factor transportation into the total purchase price. See our guide to shipping a car and review car shippingcosts before comparing an out-of-state vehicle with a local alternative.

7. Kelley Blue Book: best for determining if the price is fair

Kelley Blue Book probably isn't the first place you want to start looking for cars for sale, compared to the other sites on this list. Instead, it's more of a resource for evaluating the Fairness of a particular listing you've found elsewhere.

An important clarification: Kelley Blue Book and Autotrader are owned by the same parent company, Cox Automotive. Consequently, KBB valuations should be viewed as a completely separate and "independent" second opinion regarding an Autotrader listing. The reason is that they are based on the same dataset.

Why it is beneficial

• Kelley Blue Book’s "Fair Purchase Price" indicates the amount buyers can expect to pay for a specific vehicle in the current market.
• Fair Market Range shows a range of typical sale prices rather than suggesting a single expected price point.
• Good companion resource to marketplaces

Best used when…

You've found a listing elsewhere and want to make sure the asking price seems fair.

Limitations

• In most cases, this is not the place to start your search.
• Fair value estimates serve only as a general guideline.
• They reflect broad market trends but do not account for specific local factors - such as supply-and-demand imbalances or the specific condition and amenities of a listed property.

Who is it suitable for?

Anyone who wants to research a particular asking price before viewing/test-driving.

8. AutoTempest: best for comparing multiple marketplaces

AutoTempest is a tool for sifting through multiple marketplaces at once. It aggregates results from sources including Cars.com, eBay Motors, Carvana, TrueCar, Hemmings, and Cars & Bids, while also helping shoppers continue searches on platforms such as Autotrader, CarGurus, Craigslist, and Facebook Marketplace.

What makes it useful

• A time-saving way to browse multiple marketplaces at once.
• Helpful for ensuring that you aren’t missing any specific listings, especially those that might otherwise be challenging to find.
• Good for shoppers seeking a specific vehicle type and/or those who want to compare multiple sources.

Best used when…

You want to ensure that you aren’t missing any potential listings.

Limitations

• It’s a research assistant, not a marketplace in and of itself, so you still need to do due diligence on any particular listing.
• Applicable taxes, fees, and charges depend on the underlying source, as does the overall fairness of the asking price.

For whom it’s recommended

Shoppers who want to avoid spending hours sorting through any one given search engine.

9. AutoNation: best for shoppers who prefer a large dealer group

AutoNation is more of a large dealer group than a "search engine"-style marketplace, but that doesn't necessarily rule it out for shoppers who prefer buying from large dealer groups rather than independent sellers.

Why it's different

AutoNation lets you browse inventory from a large dealer group rather than individual sellers. If you want a more traditional dealership-type experience with wide reach, this could be a good fit.

Practical considerations to be aware of

AutoNation is a good fit if you want:

• Large-scale retail presence (physical locations) with dedicated used-vehicle operations.
• AutoNation 1Price no-haggle pricing on used vehicles.
• Five-day/250-mile money-back guarantee on used vehicles, subject to AutoNation's conditions.
• Ability to combine online research with physical assistance.

Limitations

The obvious caveat is that you're looking at one dealer group's inventory, not an aggregation of inventory from multiple sources. As such, it's probably best to treat this as a buying tool rather than a research tool.

Best if...

You're looking to buy from a large dealer group rather than from independent sellers.

10. eBay Motors: best for nationwide and hard-to-find vehicles

eBay Motors is a great place to look beyond the local dealer and other popular sites. It lists vehicles from both dealers and private owners, making it a good place to find older, specialty, enthusiast, or otherwise unique vehicles.

What makes it useful

• With a nationwide reach, you can find vehicles that wouldn't show up in a local market search.
• Both dealers and private-party sellers contribute listings.
• It can help you find a specific vehicle model, trim, configuration, or something older.

Limitations

• You'll need to be especially diligent when researching a vehicle you can't see in person.
• Shipping costs can make or break a deal.
• In most cases, the price of a listing depends on the seller.

If you find a good deal on a car for sale in another state, factor in the total cost once it gets to your driveway. You should also explore your options for shipping a car to your location, and use our car shipping cost calculator to get an idea of what to expect for a purchase you can't test drive in person.

11. Manufacturer portals for certified pre-owned (CPO): a smart choice for pre-owned vehicles

Searching manufacturer CPO portals is a good choice if warranty coverage and vehicle condition matter more than getting the lowest possible asking price.

Why it’s good for buyers

• CPO vehicles generally have to be in better condition than your average used car, based on age, mileage, and other criteria defined by the manufacturer.
• CPO cars typically come with at least some added warranty coverage from the manufacturer beyond what you’d get with a regular used vehicle.
• Searching the manufacturer’s own CPO website helps you find certified inventory at multiple franchised dealers.

Drawbacks

• Fewer selection than you’d find on a general used vehicle marketplace
• CPO vehicles tend to have higher prices than similar non-certified used vehicles at the same dealership
• Certification criteria, warranty coverage, and added benefits vary by manufacturer

Who it’s best for

Buyers who want to pay more for the reassurance of a manufacturer-certified vehicle and process that includes more thorough inspections and higher standards for mechanical condition and appearance.

12. Private-party and local listing sites: best for bargain hunters who want to do their own due diligence

While these local listing sites aren't necessarily the best places to find used cars for sale, they can sometimes turn up attractive local private-party deals.

Craigslist charges private sellers a fee for by-owner vehicle listings, while Facebook Marketplace generally allows private sellers to list vehicles without a listing fee.

Pros

• Can uncover less expensive cars for sale.
• Best for local cash purchases.
• Can sometimes find vehicles that aren't available on the larger marketplaces.

Best use case

These sites work best for consumers who know what they're looking for and how to ensure a fair deal.

Cons

• More prone to scams (curbstoning, fake escrow, VIN cloning, title washing)
• Variations between what is shown in photos/in the description and the actual condition of the car
• Takes more time to find a good listing and go through many pictures and descriptions

FTC reported in September 2026 that fraudsters are already cloning legitimate car dealers' sites (using AI) and stealing logos, listings, pictures, and fake reviews to take payments for a car they do not have. Also, BBB Scam Tracker data shows that the median loss for scams involving sales and escrow vehicles is $12,600.

Do not send money via a wire transfer or an escrow service recommended by the seller. Double-check the seller’s or dealership’s information before sending any money, especially if you can’t examine the car before buying.

Who Should Use These Channels?

Bargain hunters willing to spend time looking through private party listings.

Why using multiple used car websites is a better approach

Some car shoppers tend to stick to a single platform to browse and research vehicles they want to buy. There are a number of benefits that the multi-platform approach provides car buyers, including:

• Combining car listing websites and price guides, such as KBB or CarGurus, helps buyers research whether a seller's asking price is fair for a specific make and model's market value.
• Researching certain makes and models on separate sites, especially before test-driving a vehicle at a local car dealership, can help you avoid buying a car with major issues based on the seller's potentially misleading description of its overall condition.

Comparing the same car on multiple sites

It may also highlight discrepancies between what certain car dealerships and websites list about a car's features and its actual selling price.

It may also help potential car buyers research certain car dealerships to see if there are any negative customer reviews before making an appointment to physically view and test-drive a particular vehicle.

Lastly, while CarMax and Carvana are convenient options for car shoppers who want a seamless car-buying experience, buyers should compare and contrast the asking price of a specific car on both dealership websites and similar vehicles in their area before making a purchase.

For out-of-state purchases, potential buyers also have to factor in the cost of shipping a car to their location. A seemingly affordable car purchase may quickly balloon in price because of additional costs, including taxes, fees, and a car inspection upon arrival in most states.

Which website is best for second-hand cars?

There isn't one best website for used cars. Here's the breakdown, by best fit:

• Biggest inventory: Autotrader, Cars.com
• Pricing insight: CarGurus, KBB
• Research: Edmunds
• Easiest buying process: CarMax
• Online-only convenience: Carvana
• Hard-to-find or nationwide vehicles: eBay Motors
• Certified used vehicles: manufacturer CPO portals
• Local private-party hunting: Craigslist, Facebook Marketplace, local classifieds

Most Americans will want to cross-reference two or three sites anyway, and that's not using any one site to its fullest potential.

Is CarGurus a reliable source?

CarGurus can be a reliable shopping source, but that's different from saying every individual entry on the site is reliable.

Here's how you could assess that:

Yes, reliable for finding and comparing. It is not so much for researching individual vehicle condition, accident history, maintenance records, title status, or dealer practices.

CarGurus is a useful tool, but it shouldn't be used in a vacuum.

Is Carvana or CarMax better?

It truly depends on the situation. The two main factors that set these services apart are their return policies and how they evaluate the vehicle.

• Return window: Carvana offers a 7-day return window, whereas CarMax offers a 10-day Money Back Guarantee.
• Included warranty: Carvana has a 100-day/4,189-mile limited warranty, while CarMax currently provides a 30-day limited warranty with no mileage limitation, depending on the state.
• Delivery and test drive: Carvana is strictly a delivery- or vending-machine-style purchase, with no option for a pre-purchase test drive. CarMax lots are pickup locations; test drives are available, and delivery is an option for some.

Price can be a big factor when purchasing a vehicle. According to iSeeCars, compared to private-party listings, CarMax had an average markup of 4.2%, compared to 3.9% for Carvana. The data used in this study was not current when this article was written, so these numbers do not reflect the current market value. However, this data still shows that both popular buying methods have a slight markup, depending on the region.

It's hard to say which of these two sites is better. It depends on the buyer's needs and wants. Both sites have their pros and cons, but they appeal to different markets. No site caters to everyone, so buyers should research based on the vehicle, price range, and location.

What to look for regardless of the website

Even the best used-car websites can't cover a lack of buying knowledge.

Before buying:

• Make sure of the final price (out-the-door), not the sticker price.
• Ask for the vehicle identification number (VIN).
• Check a vehicle history report, if available.
• Make sure there are no undisclosed accidents or title liens.
• Check service history, if possible.
• See the car in person if possible or have it inspected if not.
• Test drive.
• Review any additional charges, options, and financing terms.
• If shopping at a car dealership, research the dealer's reputation elsewhere.
• Compare vehicles to a couple of similar ones before buying.

The biggest mistake is to rely on the website more than the actual listing.

Practical suggestions by priority

• If you're looking for the most inventory
• If you're looking for the best prices
• If you're not sure what you want
• If you want the easiest buying process
• If you're looking for local private-party deals
• If you want the smartest buying process

Use a combination of the best resources:

• Edmunds for research
• Autotrader or Cars.com for inventory
• KBB or CarGurus for pricing
• CarMax or Carvana for convenience, if desired

Frequently asked questions

What is the $3000 rule for cars?

You may have heard of the "3,000-dollar rule." It is not an industry standard. People use this expression in various ways. One common interpretation is to have at least $3,000 in cash available toward the purchase or down payment (rather than a specific amount the vehicle should be worth), leaving room for registration, maintenance, and repairs costs. It is always important to leave room for maintenance and repair bills after the purchase.

Bottom line

The best used car websites aren't a single site, but a curated small collection.

For most buyers, the best combination will include a research site, an extensive listing site, and a price-checking tool. Using just one site makes you more likely to miss a vehicle, miss a better deal, or overlook a warning sign. Using two or three, when done correctly, improves your odds of getting exactly the right used car - at the right price.
