Winner

AutoTrader

  • $49 to list your car for sale
  • KBB Instant Cash Offer
  • Include up to 30 photos at no extra charge

Autotrader is a popular platform for buying and selling cars, offering both instant offers from dealerships and private listings with the help of Kelley Blue Book. With Autotrader, you can get an instant cash offer from a participating dealer or list your car privately, and the company's secure payment system makes the transaction process easy and hassle-free. While some users have reported negative experiences with private listings, Autotrader's instant offer option has received positive reviews, making it a competitive choice for those looking for a quick and fair sale.

CarMax

  • Sell directly to CarMax
  • Payment at time of drop off
  • Free KBB price comparison

CarMax is a well-known used car retailer that offers a hassle-free car buying and selling experience, with a "no-haggle" pricing policy and convenient features like 24-hour test drives and home delivery. While they may not offer the highest prices for your vehicle, they're a good option for those looking for a straightforward and stress-free sale, with payment available on the same day at one of their locations. However, some users have reported mixed reviews and lower-than-average offers, so it's worth shopping around and comparing prices before making a decision.

When it's time to sell a car, many of us still reach for the old playbook: plug the details into Kelley Blue Book to get a number, then head to a dealership hoping they'll match that KBB figure. That approach made sense for years when options were limited. Now the landscape's different - online marketplaces have reshaped how cars are bought and sold, pushing those traditional routes into the rearview. Many of these platforms offer instant valuations, wider reach, and even at-home pickup, making the process faster and more transparent.

Forget sticking a "for sale" sign on the windshield and waiting for someone to show up; these days, most people sell their cars entirely online, and it's usually quick and painless. With a host of pricing tools and real-time market data, you can set a competitive number and reach buyers well beyond your neighborhood. You can list on multiple marketplaces in minutes - add clear photos and a detailed description to stand out - and watch qualified inquiries roll in.

When it's time to sell your car, most car sales sites present two routes: take a cash offer from a dealer - either online or at a nearby lot - or create a private listing. Both come with trade-offs. Choosing a dealer is the easy path because you avoid vetting buyers, juggling back-to-back showings, and figuring out secure payment, and some online services will even pick up the car from your address at no extra cost. A private listing can take more time and effort, but it may help you get a higher price.

Convenience can carry a trade-off: many cash-for-cars services won't take every vehicle, and selling privately can sometimes net you more. Because individual buyers aren't covering a dealership's markup, they'll often pay closer to true market value - which lets you open with a higher asking price. That said, a private sale usually demands more time for photos, messages, and test drives, so weigh speed against potential profit. Some sellers even get a quick pre-sale inspection to build trust and justify their number. Plenty of people hedge their bets by doing both, gathering instant offers while also posting a private listing to see what the market will bear.

No matter how you plan to sell your car, have the basics ready: current registration, any key fobs and manuals you've got, a valid state-issued photo ID, and all owners listed on the title present for the handoff. Exact paperwork can vary with your state's rules and the service you choose, so check their requirements ahead of time - it'll save time and headaches. Staying organized from the start makes the sale smoother.

With so many sites to help you sell your car online, it can be hard to know where to start. To help you make an informed decision about which one is best for you, consider the following criteria:

Car Selling Site FAQ

Can I really sell my car online?
Yes! The days of taking out an ad in the classifieds are gone - most private sellers sell their cars by listing them online. The process is simple and makes it possible for thousands of prospective buyers to see your vehicle.
How much does it cost to sell my car online?
Nothing! There are several sites that allow you to list your car for free. Of course, most of these sites offer upgraded listings for a fee, if you'd like to put up more photos, have your ad up for longer than 30 days, or include your vehicle's CARFAX report.
How can I get the most money for my vehicle?
Start by determining a fair market value for your car: most people use Kelley Blue Book to do that. Then, make sure your vehicle is reasonably clean - you don't have to spend a lot of money for a professional detailing, but at least make sure to wash it well and do a thorough job of cleaning out the inside (no crumbs, fast food wrappers, or unpleasant odors!). Finally, set up your online listing for maximum visibility: the more information you provide, including photos, the more prospective buyers you'll get.
What paperwork do I need to sell my car?
At the very least, you'll need to have the vehicle's title in hand (or available for electronic transfer at your DMV). If you still owe money on your car, contact your lender to find out their process for getting the title. Other paperwork that can help you sell your car includes documentation of the service history (e.g. oil changes, tire rotations), initial purchase documents if you bought the car new, and a vehicle history report from a service like CARFAX.
Someone wants to see the car. What do I do now?
For safety reasons, you may want to arrange to meet at a neutral public location like a parking lot or even outside of the police station. If the buyer wants to take a test drive - as they should! - you should get a photo of their driver's license and be sure to ride along with them.
Can I sell my car directly to a dealer?
Absolutely! While you may not get as much money for your vehicle this way, it eliminates a lot of the hassle you'll experience when selling to a private buyer. There are online services that specialize in advertising your car only to dealerships. You could get an instant cash offer, or a dealer might ask to do an in-person appraisal first.
Should I pay for an inspection before I sell my car?
That's up to you, but a smart buyer will probably request one from a mechanic they trust instead of taking yours at face value. It might be better to wait until you have a buyer and let them choose if and where to have an inspection done.
I've sold my car. When can I cancel my car insurance?
Call your insurer! If you're planning on getting a new car, you may have to keep your policy in place so that there's no lapse in coverage.
