These are the best used car websites, our research shows

Shopping for your next used car?

Then you probably are spending a lot of time online at used car websites.

About 80 percent of the millions of used car shoppers each year spend nearly two-thirds of their research and shopping time – or about 10.5 hours – on used car websites, such as Autotrader, Edmunds and (Kelley Blue Book).

But determining which are the best used car websites that help most may seem as challenging as finding the vehicle itself.


An analysis by Santander Consumer USA identified nearly 100 online research and shopping resources available to the nearly 40 million consumers that shop for used cars in a typical year. The best used car sites were named by 28 sources that listed choices for those most helpful to car shoppers.

But who has the time to look at 100 websites?


Few shoppers look at even a half-dozen of the best used car websites, based on a recent survey, which showed that online shoppers visit an average of about four websites before buying their used vehicle, and that third-party websites typically were the first and last online shopping destinations.

You may use more or less than four of the best used car websites, but you probably still want to know which research and shopping websites are likely to be the most helpful so you don’t waste your time.

Here are our 16 best used car websites in order of how often they were identified in our survey:

The 16 best used car websites


Not all third-party websites are right for every search and using the wrong one can waste your time. Our goal here is to help you focus on the best websites for your research and shopping. Here’s what you need to know about the 16 used car websites that topped our survey:

Best online car-buying websites to get results

While the survey is one way to look at the best used car websites for shoppers overall, some shoppers already have done their homework and just want to search for a specific vehicle.

We sampled all the best used car websites in the list above by searching for 2015-2017 Ram 1500 pickup within 50 miles of a specific location in the suburb of a major metro area. Three- to five-year-old models fall in the “sweet spot” of used vehicles with the big depreciation hit having been taken by the original owner and still offering recent features and technology, as well as possibly lower maintenance costs.

That generated this ranking of the 13 best online car-buying sites based on search results shown in parentheses:

• (664)
• (447)
• Facebook Marketplace (428)
• (384)
• (360)
• CarGurus (292)
• Kelley Blue Book (290)
• Autotrader (268)
• (268)
• (255)
• (177)
• Carvana (172)
• CarsDirect (159)

Of course, results may vary depending on where a shopper resides, the specific model they are seeking and how far they are willing to travel from home to purchase a vehicle.

While most vehicle shoppers won’t want to use their average of 10 hours of online research and shopping time based on quantity alone, there’s something to be said for using at least one comprehensive website that provides information on the local market.

Otherwise, choice of the best used car sites depends a lot upon what other information the shopper wants or needs to make the best vehicle-purchase choice to fit their lifestyle.

But, as we wrote at the outset, there are a lot more third-party websites than time to look at them.

What the best online car-buying sites provide shoppers

Before you spend precious time on any of the third-party resources – even the best online car-buying sites – it might help to know why it’s worth the effort for serious car shoppers.As you might expect, third-party websites were happy to talk about their value to shoppers.

“Third-party websites allow shoppers to search cars from multiple dealerships and compare listings across multiple makes, models and vehicle types,” said Julie Blackley, a spokeswoman for “Along with showing more inventory than what can be found on dealer websites, the best third-party sites arm users with the data necessary to make a smart vehicle purchase.”

“In today’s digital world, shoppers want to be able to comparison shop and narrow down their car search by visiting as few websites as possible,” she said. “Ideally, shoppers will be able to comparison shop and narrow down their car search by visiting just one website.”

Representatives of Cox Automotive (Kelley Blue Book and Autotrader) offered similar views.

“Third-party sites have played a critical role in connecting consumers with a marketplace of inventory and with dealers across the country when they’re shopping for a vehicle,” said Cox’s Rachelle Petusky, who cited the need for “a personalized, intuitive experience” and getting a great deal.

“The best third-party automotive sites are trusted, comprehensive and easy to use,” said Jason Allan, editorial director for Autotrader and Kelley Blue Book. “By providing unbiased reviews, ratings and pricing guidance, many third-party automotive websites make it much easier for shoppers to triangulate their way to the right car and a fair price.”


“Unbiased transparency is far and away the most important factor that a shopper wants from a third-party platform,” said a spokesman for CarGurus website.

What shoppers value most from third-party sites

There’s nothing complicated about what shoppers value at third-party websites, suggests Mark E. Roszkowski, chief revenue officer at Vroom: selection and convenience.

“Used cars are all different and buyers appreciate having multiple makes and models to choose from, with varying levels of mileage, options and features. When you give consumers access to thousands of vehicles to choose from, they don’t have to compromise on getting exactly what they want.”

And now, more than ever, he said, “Consumers value the ability to buy or sell a vehicle without ever leaving home. They can shop and transact when it’s convenient for them, not others.”

A spokeswoman for third-party website TrueCar said consumers also want a “personalized experience.”

“Whether it’s shopping from home online or going to the dealership, needing to trade a vehicle or shopping for a used vehicle, consumers like to have options and need a personalized experience,” the spokeswoman said. “A third-party website that can provide consumers that kind of experience without having to visit multiple sites during the process stands out from the crowd.”

“The ability to do everything online is a huge advantage and differentiator,” said Vroom’s Roszkowski. “Brands that offer end-to-end digital retailing – for buying, selling, trading, financing, delivery – are serving a true consumer need for a convenient, seamless experience.”

Petusky of Cox Automotive stated the consumer value proposition in even simpler terms.

“The sites that win are the ones that can meet consumers where they are in their shopping or ownership journey with information that gives them confidence.”

The COVID-19 effect on shopping behavior

The COVID-19 pandemic brought the best used car websites front and center, with sites we surveyed reporting dramatic increases in usage since early in 2020.

And an expectation that the pandemic may have changed the landscape permanently.

“We actually saw record-breaking traffic on weekends as consumers shopped virtual lots online instead of physical lots,” said a report from Cox Automotive. This activity has translated to “real buying actions” with a 360% increase in the number of digital retailing “sends” to sellers on Autotrader.

“ has seen a significant increase in traffic – 50% to 100% depending on the month – since COVID-19 in response to heightened demand for used cars and for private transportation,” said Blackley.

“Interest in digital retail has surged as the result of the pandemic,” reported CarGurus.

Before the pandemic, “35% of respondents said they were open to buying online,” according to a CarGurus report from November of 2020. “Now, 60% of respondents are open to the idea.”

“Shoppers expected they’d return to their normal shopping habits fairly soon – which most have come to accept is no longer the case,” CarGurus observed. “As the pandemic continues, comfort and familiarity with online tools grows. Now, car shoppers increasingly consider digital retail.”

“Third-party listing sites should have features in place to help shoppers navigate this new COVID-19 environment,” said the CarGurus spokesman, who went a step further. “This includes empowering shoppers to filter for dealerships that provide a variety of safe features, including contactless purchases, free home drop-off, free at-home test drives, private dealer appointments and virtual appointments.”

The bottom line on using the best used car sites

Third-party car-shopping websites that have been built with a “consumer-centric mindset” are the ones that shoppers will visit regularly as they go through their buying process.

“The average user visits [third-party sites] 12 times before buying, making them the most widely and frequently used auto resource,” according to CarGurus’ 2020 Buyer Insight Report, which analyzed the car-purchasing behavior of more than 3,000 consumers.

“The reason behind this high engagement is because third-party sites … provide a wide variety of pertinent information to help make this major purchase,” said a spokesman.

But the usefulness of the best online car-buying sites goes even further, CarGurus suggests.

“Shoppers today are accustomed to using online to make them smarter shoppers. Whether they’re buying cleaning products or a car, shoppers will dig through ratings and reviews to ensure they’re being treated fairly. Both in terms of price and quality.”

Of course, that takes us back to our original premise: determining the best used car websites may seem as difficult as finding the vehicle itself.

Our lists of the 16 best used car websites based on a survey of online sources and 13 that get proven search results based on our own research should make it a little easier to identify those third-party websites which may be the best used car sites in your search for another vehicle.

Even better if you find three or four of the best used car sites to make your shopping an adventure rather than an ordeal.
