A 2025 study by Cox Automotive showed that 75% of car buyers used a third-party site during the shopping process. While there are many third-party auto sites available, three popular options for searching new, certified pre-owned, and used cars are AutoTrader, CarGurus, and Cars.com.
On the surface, the sites look very similar. They offer a search box, pages of dealer inventory, and a little price badge on each listing. However, differences appear when you want to sell a car yourself, decide whether an asking price is fair, or line up a loan. Some differences among the sites have changed in recent years, so we’ll look at how CarGurus vs Autotrader vs Cars.com compare in Fall 2026.
Buying
For buyers, all three sites function as search engines that let you filter by make, model, price, mileage, and distance from your location. They also offer services that can help buyers with financing and avoiding scams, especially when buying out of state. Most results show vehicles in dealer inventories, though private seller sales are where Autotrader and Cars.com fight it out.
AutoTrader, part of Cox Automotive, leans on its sibling brand Kelley Blue Book. Most listings carry KBB pricing information, and cars sold through AutoTrader's private-seller service are also posted on KBB.com.
CarGurus made its name with its sorting function. Its search puts the listings it rates as the best deals at the top, and the company says that order comes from its algorithm, “not how much a dealer pays us.” More than 13,000 dealers take part in its Digital Deal program, which lets a buyer work through trade-in and payment steps before walking into the store.
Cars.com, now owned by Cars Commerce, offers the same kind of dealer-heavy search with its own deal badges and dealer reviews. Its edge is less about buying and more about what happens when you want to sell a vehicle.
Selling and Private-Seller Options
Selling your car online is where the three platforms split apart and largely becomes an AutoTrader vs. Cars.com battle.
AutoTrader runs private sales through its Private Seller Exchange. The seller pays a $49 listing fee plus a service charge of $99 or 0.99% of the sale price, whichever is greater. On a $15,000 car, that charge is $148.50; on a $35,000 car, it is $346.50. For that money, AutoTrader provides substantial value, including:
- Verifying the identities of buyer and seller
- Holding the buyer's funds
- Handling the title transfer
- Supplying an AutoCheck history report
- Processing the registration in some states.
It does not handle pre-1990 cars, salvage-title vehicles, and leased cars. Sellers interested in speed over price can request a Kelley Blue Book Instant Cash Offer redeemable at participating dealers.
CarGurus stopped allowing private listings in 2024. While you can no longer sell your car to another customer through the platform, you can use the Sell My Car function to receive offers from dealers. The offers are good for seven days or 250 miles, with home pickup available in some states.
Cars.com is the only one of the three that lets you list a car privately at no cost. Its sell page:
- Has “no costs or hidden fees”
- Listings typically go live within about 24 hours
- Requires photos
- Cars that are 1992 model or newer
For sellers who want a protected transaction, Cars.com partners with Caramel, which handles financing, vehicle protection, insurance, and delivery for verified buyers. Cars.com also offers an Instant Offer from local dealers. That offer is good for three business days and is confirmed by an inspection at the dealership.
Price Evaluation
All three sites grade listings against an estimated market value, but they do it differently.
AutoTrader:
- Uses the Kelley Blue Book Price Advisor, which shows a Fair Market Range instead of a single number.
- A price in the green zone is considered fair to both sides, and listings may be tagged “Great Price” or “Good Price” depending on where they fall in that range.
CarGurus:
- Calculates an Instant Market Value, an estimated fair retail price drawn from comparable current and past listings, updated daily.
- Each car is rated as Great, Good, Fair, High, or Overpriced. It is the only one of the three that openly flags a car as overpriced.
Cars.com:
- Shows deal badges based on more than 100 variables, including local supply and demand, vehicle history, certified pre-owned status, and dealer ratings.
- Badges range from Great Deal to Fair Deal.
- Cars.com doesn't use a car's asking price to predict its market value, and some vehicles get no badge when there isn't enough comparable data.
None of these ratings is an appraisal. As a potential buyer, treat a badge as a starting point for negotiation, then confirm the car's condition with a history report and an independent inspection.
Financing
CarGurus' lender lineup includes Chase, Capital One, Global Lending Services, and Westlake Financial, and it lets shoppers see estimated rates through a soft credit check that doesn't affect their credit scores.
Cars.com offers a Get Prequalified button on listings and in its Finance Hub, also using a soft pull. Cars.com does not lend money itself; the offers come from lenders that work with the selling dealership. They call the result “an invitation to apply, not a guaranteed approval.”
AutoTrader's financing story is strongest on the private side. Buyers using the Private Seller Exchange can apply for loans through participating lenders, often get approval the same day, and close the loan online. That provides buyers with real value because financing a car purchased from a private owner is generally harder than financing a dealer purchase.
Platform Usability
Usability depends on what you are trying to do. CarGurus is the quickest for a buyer focused on price. AutoTrader provides KBB valuations in the lists, so it works best for shoppers who rely on Kelley Blue Book. Cars.com is the least complicated way to sell a car yourself, with no fees and an optional transaction partner.
If you plan to buy from a dealer, consider using all three platforms, since they cost nothing to search, they can include different dealers, and the difference in who they rate vehicles can be informative.
If you are selling, Cars.com is the free do-it-yourself option. AutoTrader charges more but offers identity checks, payment, and title work. CarGurus is now strictly a place to collect dealer offers.

FAQs
Do AutoTrader, CarGurus, and Cars.com show the same vehicle listings?
For dealer cars, there is a lot of overlap, but the three are not mirror images. Most dealers push a single inventory feed out to several marketplaces at once, which is why the same car often shows up on all three sites.
The differences come from who is on each site. Each one has its own dealer roster. Cars.com reported about 19,500 dealer customers in the U.S. and Canada at the end of 2025. CarGurus lets dealers list inventory for free, with limits, so its results can include stores that don't pay it for advertising.
Private-seller cars split even more: CarGurus doesn't have any, AutoTrader's Private Seller Exchange cars appear on AutoTrader and KBB.com, and Cars.com's free private listings stay on Cars.com. Even when one car appears on all three, it can carry three different deal ratings, because each site evaluates cars using its own model. Searching all three is still the best way to see the whole market.
Are there any fees for buyers using AutoTrader, CarGurus, or Cars.com?
Searching listings, contacting sellers, and checking financing prequalification cost nothing on any of the three. The sites make their money from dealers, so fees show up only when you use a private-sale transaction service.
AutoTrader says buyers using its Private Seller Exchange pay no surcharges or premiums, just the price of the car plus sales tax and registration where required. One exception: in most states, when a buyer pays cash, the exchange collects a fee to cover getting the title from the seller and making sure it is completed correctly.
On Cars.com, private sales handled through its partner Caramel carry a buyer document processing fee of $95 if the buyer does the title and registration, or $195 if Caramel does it, rising to as much as $295 in complicated cases. The seller can agree to cover the $95 fee. CarGurus has no private sales, so it has no buyer transaction fee.
Do these platforms provide vehicle history information for used cars?
Each platform offers vehicle history reports, though their sources may differ. For CarGurus vs AutoTrader, CarGurus pulls data from AutoCheck, and AutoCheck flags appear automatically in the Vehicle History section of the listing. Meanwhile, AutoTrader links many listings to a free CARFAX report, and buyers using its Private Seller Exchange get a complimentary history report. Likewise, Cars.com has long offered free CARFAX reports on listings from participating dealers.
Before you buy, run the VIN through an NMVTIS-approved title check, check for open recalls, and have a mechanic of your choice inspect the car.
