Our 3 favorite online car buying sites

We were selective when choosing our top three picks for online car sites. First, we studied consumer reviews, only choosing trusted sites with the best buyer analyses. Second, we made sure each of our top picks for best online car buying sites had a wide selection of vehicles. Last, we considered pricing, apps and online experience.

Whenever you buy a car online, make sure the person or dealership you’re buying from is legitimate. If something feels wrong, it probably is. Consumer reviews are always a good place to start to see what other people think of a particular online car dealer.

If you’re worried about scams, then only buy cars online from certified dealerships instead of individuals. Read on to learn more about the best sites to buy and sell cars.

Our favorite car buying site

Company nameContact
  • New and used vehicles
  • Flexible pricing
  • Instant Market Value highlights best deals

What we like: The magic of CarGurus starts with its search engine. They have over five million new and used cars listed on their website, and you can use filters like make, model, year and ZIP code to focus local deals. Each vehicle in the search results is labeled as one of the following: Great Deal, Good Deal, Fair Deal, High Price or Overpriced.

Once you click on a car, you can look at the listing history, which shows how long the car has been listed on the site and its pricing history. If a price has been fixed for a long time, you might be able to ask for a lower price. You can also sign up to be notified when a car’s price drops.

Additional features:

  • Test drive videos and preview upcoming cars
  • Vehicle history reports
  • Payment calculator
  • Question and answer forum
  • User reviews
  • Companion app for Apple and Android

What to consider: Technically, anyone can post a car on the CarGurus site. For this reason, it’s important to make sure the posting is legitimate. One way to do this is to buy a car through a certified dealership on the site.

Next, it’s free to view the summary of a vehicle history report, but CarGurus charges money to see the entire report.

Finally, you should know that sponsored listings often appear at the top of search results. These sponsored results sometimes don’t match the search filters, but they are clearly marked, so it’s easy to know what’s promoted and what isn’t.

Our favorite car buying app

Company nameContact
  • New and used vehicles
  • Flexible pricing
  • Highly rated mobile app

What we like: You may be familiar with AutoTrader as a magazine, but it’s also a comprehensive online site for buying and selling cars.

In addition to being a great online car buying site, Autotrader also has highly rated apps for Apple and Android. In the app, you can search for cars, save cars to your favorites and connect with sellers. Dozens of search filters allow users to pinpoint the exact car they are looking for.

Through Autotrader’s intuitive search engine, you’ll be able to find new and used cars from professional and private dealers nationwide.

Additional features:

  • Comparison tools to view several cars side-by-side
  • User reviews
  • Resources on warranties, car insurance and financing
  • Free quote for Geico insurance
  • Affordability calculator
  • Vehicle top ten lists
  • Financing through LendingTree
  • Vehicle history reports

What to consider: There are over three million cars for sale on the Autotrader site. This can be overwhelming, so don’t be afraid to narrow down your search using filters. It’s also important to know that the car loans option on Autotrader will direct you to an outside source, LendingTree, which is an online auto loans broker. Last of all, promoted cars show up at the top of the search results, so make sure to scroll down a bit further, as these featured cars won’t always match your search filters.

Our favorite used car buying site

Company nameContact
  • Used vehicles
  • Fixed pricing
  • 7-day money-back guarantee

What we like: We like that Carvana’s cars are highly curated to ensure the highest quality of vehicle. Cars that have been in an accident are not allowed to be sold on Carvana, and Carvana runs an Experian auto report to confirm this. Carvana also performs a 150-point inspection to make sure each vehicle is fit for purchase.

Carvana actually owns the cars it sells, so you can speak directly to Carvana instead of an unknown dealership or individual seller. The prices on Carvana are fixed, so this means no haggling. We like this because it provides transparency and helps you know what you’re getting. 360-degree photos are available for every car online in order to simulate the experience of seeing the car in person.

Once you buy the car, it will be delivered in 48 hours. If you prefer to come to the Carvana center to pick up your vehicle, take advantage of their Fly and Drive option.

Additional features:

  • Financing available, even for those with poor credit
  • Every car cleaned to look like new
  • Free oil change
  • Limited 100-day bumper-to-bumper warranty
  • 7-day money-back guarantee

What to consider: Unlike some other big car buying websites, the amount of vehicles on Carvana numbers in the ten of thousands rather than the hundreds of thousands. However, there still is a wide selection of cars, and they are highly curated for quality.

Although it costs money to ship a car to your current location, if you’re near a Carvana hub in Atlanta, Birmingham, Charlotte, Dallas or Nashville, you can pick up a car for free. If you are between 75 and 250 miles away, the cost is $199. It’s $1,000 for even longer distances. You also never get to test drive a car, but you can return it after 7 days if you don’t like it. Last of all, if you trade a car in, you have to deliver it to one of Carvana’s local sites yourself.

Check out how Carvana stacks up to Vroom and Carmax.

Questions to ask when buying a car

If you’re unable to find certain information online, it’s always a good idea to ask the car dealership or individual seller a few questions, especially if the car you want to buy is used. If the seller can’t or won’t answer your questions, consider that a red flag. The questions to ask when buying a car online should vary based on whether you are buying a used car or a new car.

Questions to ask when buying a new car

It’s easy to get caught up in the excitement of buying a new car and forget to ask the right questions. Although the car is new now, one day it will be old, so make sure you know how to best take care of your car and if it fits your current needs.

Can you buy a car online and have it delivered?

It’s important to ask if the vehicle can be delivered and if there is a fee for delivering it. If you are willing to pick up the vehicle yourself, or if you live within a certain radius of the pickup location, pickup will be free. If you live far away, however, fees can quickly add up to $1,000 or more.

Do you have a car that fits my needs?

If you were buying a car in person, you would ask a salesperson this question. In the case of an online car buying site, the site’s search engine should do that work for you. If you don’t have any luck finding a car that meets your specifications, don’t give up. Instead, try a few other online car buying sites to see if you can find another one that works for you. If you have trouble finding matching cars on several sites, either wait a bit and try again, or loosen the restrictions you’re using, starting with the least important feature.

What do repairs typically look like for this make and model?

Sometimes it can be hard to get an answer on this one, so it might help to look at other user reviews online for answers. Look for patterns in repairs, and factor these into your budget.

What’s the gas mileage?

This is an important question to ask when you are budgeting for a car. If you are shopping online, this information should be available on each vehicle’s individual page.

Does this vehicle have 4 wheel drive?

All-wheel drive (AWD) and four-wheel drive (4WD) help with traction and acceleration when driving on slippery surfaces or in inclement weather. They typically cost more and require more maintenance than two-wheel drive (2WD). If this is important to you, make sure to ask about it.

Are there any additional fees?

Nothing’s more annoying than hidden fees popping up at the last minute. Make sure to ask about additional fees so you can see the full financial picture.

What does the warranty on this car cover?

If something goes wrong with your new car through no fault of your own, it’s always comforting to know you can repair it at a low price. But warranties don’t cover everything, so it’s important to know exactly what it does cover.

Is it possible to hold the vehicle?

Some car dealers will put a hold on the vehicle for you while you make your decision on whether or not to buy. Holds can range from 24 hours to a few days to even a week. It’s better to take time and think over a big decision like buying a car, rather than be rushed into it.

Questions to ask when buying a used car

You might worry that a car that seems pristine on the lot or online actually has a checkered past. But if you ask the right questions, you won’t have to worry. Ask the questions below to make sure you know what you’re getting.

Why are you selling the car?

If you’re dealing with an individual seller rather than a dealership, this is a great question to ask. This is one of many questions that will help you get a better understanding of the car’s overall health.

Is the maintenance up to date?

Some online car buying sites will provide an oil change and a car wash for a used car, but it’s good to also check whether other important maintenance is up to date.

Are service records available?

If service records are available, that’s a good sign. Make sure to review them carefully. If they aren’t readily available, that might mean the car hasn’t received proper service in the past.

Has this car been in an accident?

The best car buying websites run a vehicle history check and prohibit vehicles that have been in accidents from being sold on the site. If a vehicle has been in an accident, that is a major red flag.

Are any features not working correctly?

This is another question that will get you to the heart of the condition of the car, and also let you know what would need to be fixed, so you can have a better idea of the true cost of the car. Features like the heater and AC, turn signals, lights and audio system should all be working.

Would anything stop me from taking this car on a long road trip?

This is a good question to ask to fish out any details about how the car’s condition may be less than optimal. It’s vital you have a transparent history of a used car before buying.

Can I see the ownership history?

Most good online car buying sites will be able to provide a history of the vehicle. This will give you a better idea of the condition of the car. A history of several owners also implies something is wrong with the car.

Can I take the car to a mechanic for inspection right now?

If you are about ready to buy, this is a good question to ask. The assumption here of course is that, if the mechanic gives you the go-ahead, you will buy the car. If a dealer is reluctant to let you do this, consider it a red flag.
