Finding a used car online is easier than ever. Finding the right place to shop is a little more complicated. Some of the best sites to buy used cars simply help you compare thousands of dealer listings. Others sell their own inventory and handle much of the purchase online. Private-seller websites can connect you directly with an owner, while auction platforms may be better for enthusiast or hard-to-find vehicles.
That means there is no single used car website that works best for every buyer. The right choice depends on whether you value price comparison, a streamlined online purchase, private-seller access, local shopping, or the ability to search nationwide. And wherever you shop, the website is only the starting point. You still need to evaluate the individual vehicle, seller, title, history, inspection results, final purchase price, and cost of getting the car home.
Understand the Different Types of Used Car Websites
Before comparing individual used car websites, it helps to understand what type of platform you are using.
- Marketplaces connect buyers with dealerships or individual sellers. The platform helps you find the vehicle, but the seller generally controls the final purchase terms.
- Online retailers sell vehicles from their own inventory and manage more of the transaction themselves. That can make it easier to buy used cars online without coordinating separately with an individual dealership.
- Aggregators search or collect listings from multiple sources. They are useful when you want to cast a wider net without manually repeating the same search on several websites.
- Auction platforms let buyers bid on vehicles. Winning bids can be binding, and buyers need to understand fees, inspection opportunities, payment terms, and transportation before participating.
The most important question is therefore not just, “Does this site have the car I want?” Ask who actually owns the vehicle, who accepts your payment, what protection or return terms apply, and who is responsible for delivery.
10 Best Sites to Buy Used Cars Online
Here is a quick comparison before we look at each platform in more detail.
| Site | Type | Best For |
| CarGurus | Marketplace | Comparing listing prices |
| AutoTempest | Aggregator | Searching multiple websites |
| Autotrader | Marketplace | Dealer and private seller options |
| Cars.com | Marketplace | Comparing listings and researching sellers |
| CarMax | Online and physical retailer | Combining online shopping with store visits |
| Carvana | Online retailer | Completing most of the purchase online |
| Edmunds | Research and listings platform | Researching vehicles before buying |
| TrueCar | Dealer shopping platform | Comparing participating dealer offers |
| Facebook Marketplace | Local classifieds | Connecting with nearby sellers |
| Cars & Bids | Auction platform | Shopping for enthusiast vehicles |
These “best for” labels are editorial shortcuts based on how each service works. They are not independent test rankings.
1. CarGurus
CarGurus is particularly useful when your first question is, “Is this asking price reasonable?” Its Deal Ratings compare individual listings with CarGurus’ estimated market value for comparable vehicles. Listings can be labeled from Great Deal through Overpriced when sufficient data is available.
CarGurus says those ratings consider factors such as model, trim, mileage, options, location, vehicle history, and local market information. The important limitation is that a good price rating does not mean the vehicle itself is good. A “Great Deal” could still have mechanical problems, cosmetic damage, accident history, or expensive maintenance ahead. CarGurus itself says its deal rating is a price-comparison signal rather than a certification of condition, safety, or reliability.
Best for: Quickly comparing asking prices across similar dealer vehicles.
2. AutoTempest
AutoTempest is useful when you are tired of entering the same filters on multiple websites. It aggregates listings from several major car sites and also provides links to matching searches on other platforms where it does not directly aggregate inventory. AutoTempest says its goal is to bring millions of listings into a broader search experience.
That makes it especially useful for unusual trims, older vehicles, enthusiast cars, or nationwide searches where local inventory is limited. The trade-off is that AutoTempest is primarily a search tool. When you click through to another site, confirm the vehicle’s availability, seller information, terms, and current price on the original listing. AutoTempest does not sell the vehicles itself.
Best for: Searching several sources without starting from scratch on every site.
3. Autotrader
Autotrader remains a useful option for buyers who want access to both dealer inventory and private-seller opportunities. One feature worth checking is its Private Seller Exchange, which can support parts of a private-party transaction rather than simply giving you a classified listing and leaving both parties to work everything out independently. That can make Autotrader more appealing to someone looking at the best private seller car websites but who wants more structure than a traditional local classified. Still, check the current terms for the specific listing. Services, transaction support, payment procedures, eligibility, and fees can change.
Best for: Buyers who want dealer listings and structured private-seller options in one search.
4. Cars.com
Cars.com works well for buyers who want to move between vehicle research and actual listings without changing platforms constantly. The site connects shoppers with both dealerships and private sellers. Cars.com makes clear that it provides the marketplace rather than selling or financing the vehicles itself.That makes seller research important. If a vehicle looks appealing, ask the dealer or owner for a complete breakdown of the purchase price rather than assuming the advertised number is what you will actually pay. Taxes, registration, documentation charges, dealer-installed products, warranties, delivery, and financing can all affect the final amount.
Best for: Comparing vehicles while researching the dealership or seller behind the listing.
5. CarMax
CarMax may suit buyers who want an online search but still like having physical locations available. You can shop online and then arrange eligible delivery or pickup. CarMax says delivery is available within a limited radius of select stores and that store-to-store shipping fees can apply. One of its better-known features is its 10-day money-back guarantee. CarMax currently says a vehicle can be returned within 10 days as long as its condition remains consistent with the condition at purchase. Transfer or shipping fees are generally separate and may be nonrefundable, subject to applicable exceptions. That does not mean buyers should skip an inspection or vehicle-history research. A return period is useful, but avoiding a bad purchase in the first place is better.
Best for: Buyers who want a combination of online shopping, physical stores, and a defined return period.
6. Carvana
Carvana takes the online-retailer idea further. Its purchase process is designed around choosing the vehicle, completing payment and documents online, and arranging pickup or delivery. Carvana says buyers can complete the purchase process digitally and schedule a delivery or pickup appointment afterward.
The current 7-Day Money Back Guarantee gives buyers a limited period to decide whether to keep the vehicle. However, there are conditions. Carvana says the delivery day counts as day one, return requests must be made within the seven-day period, and certain damage, modifications, or mileage beyond 400 miles can affect the return. Nonrefundable shipping charges may also remain excluded from the refund. So when comparing CarMax vs. Carvana, do not look only at the number of return days. Compare the complete buying process, vehicle price, delivery cost, return restrictions, inventory, and how much in-person interaction you want.
Best for: Buyers who want the purchase process to happen primarily online.
7. Edmunds
Edmunds is particularly useful before you are ready to buy. Its long-standing strength is vehicle research specifications, reviews, comparisons, ownership information, and pricing context. Once you narrow the shortlist, you can move into available vehicle listings. It also currently includes owner-listed used vehicles, giving shoppers another source for private-party inventory.
That combination can be useful if you are still asking questions such as:
- Do I actually want the hybrid version?
- Which trim has the features I need?
- What problems should I research?
Then, once you know what you want, you can move directly into available listings.
Best for: Research-first shoppers who want to understand the car before contacting the seller.
8. TrueCar
TrueCar is another option for buyers who prefer to compare vehicles offered through participating dealers. The value is less about private-party classifieds and more about seeing available dealer vehicles and pricing information in a structured shopping environment. As with any dealer-shopping site, confirm the actual availability of the vehicle and ask for the complete out-the-door price. An attractive listing can look very different once taxes, fees, dealer products, financing, or trade-in values are included.
Best for: Comparing vehicles and offers from participating dealerships.
9. Facebook Marketplace
Facebook Marketplace can be useful when you want to see what owners are selling nearby. Marketplace lets users search local listings and communicate directly with sellers. Meta describes the platform as allowing buyers and sellers to work out transaction details between themselves after making contact. That flexibility also means the buyer needs to do more verification.
Before paying, confirm:
- The seller’s identity
- The VIN
- The title
- Ownership
- Any outstanding lien
- The vehicle’s physical condition
Avoid treating a social profile or Marketplace listing as proof that the seller legally owns the car.
Best for: Local private-party shopping when you are comfortable handling verification yourself.
10. Cars & Bids
Cars & Bids is aimed more directly at enthusiasts. You will find performance cars, unusual SUVs, modern classics, modified vehicles, and other enthusiast-oriented inventory sold through auctions. This is not the place to bid first and think about logistics afterward. Cars & Bids currently charges buyers a 5% buyer’s fee, with a $250 minimum and $7,500 maximum. Bids are binding, and buyer fees are nonrefundable after a winning auction. The platform also tells bidders to perform their own due diligence before bidding. Transportation, taxes, inspection decisions, and other purchase responsibilities still need to be planned by the buyer.
Best for: Enthusiast vehicles when you understand auctions, fees, inspections, and transport logistics.
Which Used Car Websites Have Private Seller Listings?
If your priority is buying directly from an owner, narrow your search differently. Facebook Marketplace and Craigslist function more like classifieds, connecting you with individual sellers while leaving most of the transaction to the two parties. Edmunds currently has dedicated cars-for-sale-by-owner listings. Autotrader offers private-seller options with a more structured transaction path through Private Seller Exchange. Auction platforms can also include vehicles offered by private owners, but bidding creates a different buying process from contacting someone through a classified ad.
Before buying privately, ask:
- Does the seller’s name match the title?
- Is there an outstanding loan or lien?
- Are service records available?
- Can an independent shop inspect the vehicle?
- Does the VIN match the vehicle, title, and listing?
- Who will handle title transfer and registration?
A private seller is not automatically cheaper, more honest, or easier to negotiate with than a dealer. Evaluate the actual vehicle and transaction.
CarMax vs. Carvana: Which One Fits Your Needs?
The CarMax vs Carvana decision comes down largely to how you prefer to shop.
- Want physical locations? CarMax gives buyers the option of combining online shopping with store pickup and in-person interaction. Carvana is designed more heavily around an online purchasing experience.
- Want a longer standard return window? CarMax currently advertises for 10 days. Carvana offers seven days, subject to its mileage and vehicle-condition rules.
- Need delivery? Both offer delivery in eligible situations, but availability and cost vary. CarMax notes that delivery is limited to qualifying locations around select stores, while Carvana calculates applicable delivery or shipping as part of the purchase process.
- Comparing cost? Use similar vehicles and compare the entire transaction not only the advertised vehicle price.
CarMax may suit someone who values physical locations and store support.Carvana may suit someone who wants to complete as much of the purchase as possible from home.Neither is automatically cheaper or better for every buyer.
What to Check Before Buying a Used Car Online
No matter which of the best sites to buy used cars you choose, inspect the purchase itself.
Before committing:
- Match the VIN on the listing, vehicle, and ownership documents.
- Review a vehicle history report for reported title problems, accidents, odometer discrepancies, or other available history.
- Arrange an independent mechanical inspection whenever practical.
- Check the VIN for open recalls.
- Confirm the seller owns the vehicle and determine whether an outstanding lien exists.
- Read all warranty, return, arbitration, and “as is” terms.
- Compare the complete purchase cost, including taxes, documentation charges, registration, inspections, dealer extras, and transportation.
A vehicle history report is useful, but it cannot tell you everything about the mechanical condition of the car. A vehicle can have a clean-looking history report and still need thousands of dollars in tires, brakes, suspension, cooling-system work, or other repairs. The reverse is also possible: a reported incident does not automatically tell you how well or poorly a repair was completed. For paperwork requirements, check the DMV or motor vehicle agency in the state where you will title the car.
How to Get Your Car Home After Buying Online
Finding the right car several states away creates one more decision: How are you getting it home?
Check Whether the Seller Offers Delivery
Start by asking what the seller actually provides. An online retailer may offer home delivery.A dealership may arrange transport or transfer a vehicle between locations. A private seller or auction seller may expect the buyer to handle transportation completely.
Confirm:
- Whether delivery is available to your ZIP code
- The cost
- Who operates the transport
- When ownership transfers
- What the seller needs before releasing the vehicle
- When any return period starts
For platforms with limited return windows, that last point matters. Do not assume the return clock begins when it is convenient for you.
Compare Shipping With Picking Up the Car Yourself
Flying out and driving the vehicle home can sound cheaper until you add everything up.
Consider:
- Airline or transportation costs
- Hotels
- Meals
- Fuel
- Tolls
- Time away from work
- Insurance
- Added mileage on the vehicle
- The possibility that an older or unfamiliar used car develops a problem on the return trip
Then compare those expenses with a professional transport quote. For many standard vehicles, open car transport provides a practical way to move the vehicle. For a classic, exotic, collector, luxury, or other car where additional protection from outside exposure is preferred,enclosed car transport may make more sense. The shipping price should be part of your purchase calculation before you decide that an out-of-state car is a great deal. A vehicle that is $1,500 cheaper but requires expensive travel or transport may not actually save you $1,500.
Prepare for Pickup and Delivery
If you arrange independent shipping, make sure the seller is ready to release the vehicle.
Confirm:
- Pickup address
- Seller or dealership contact
- Pickup hours
- Any required release number
- Storage deadlines
- Whether the vehicle runs, steers, and brakes
- Any clearance or modification issues
Document the vehicle’s condition before transport and inspect it again at delivery. To obtain an interstate car transport quote, you will typically need the pickup and delivery ZIP codes, vehicle year/make/model, operating condition, and preferred timing.
Which Used Car Website Is Right for You?
The best used car website depends on how you want to shop. Use CarGurus when price comparison is the priority. Try AutoTempest when you want to cast a wide net. Look at CarMax or Carvana when you prefer a more structured retailer experience. Check Facebook Marketplace, Craigslist, Edmunds, or Autotrader when private sellers are important to your search. And if you are hunting for something unusual, eBay Motors and Cars & Bids may uncover vehicles you will not find at the dealer down the street. But the website should never make the final decision for you. Compare the actual car, seller, VIN, inspection results, purchase terms, return policy, title status, and total cost.
And if you are buying a car out of state, add transportation to the budget before you make the deal. A lower asking price only matters if the total purchase still makes sense once the car reaches your driveway. If you find the right vehicle several states away, you can get a car shipping quote from Global Auto Transportation before finalizing the purchase.
