Why use a car-buying site? Selling your car on the internet is the new norm as our buying habits continue to move online.

Selling at auction has never been much of a hit as it’s confusing, and auction fees are hefty.

List of the best sites to buy a used car.

Best used car websites to buy online

Buying a vehicle online without a test drive and negotiations seems risky. And you’d be right to think twice before buying outright. But you can put down a deposit before viewing and testing the car in person.

This section of our car-buying website reviews several leading car websites and marketplaces to find your next set of wheels.

We look at reviews, prices, and warranties to help you determine if buying a car online is suited to your personal needs.

Autotrader is one of the oldest and best online car buying sites in the UK.


Since the days of offline magazine publications, Autotrader has dominated the car buying space.

All well-known car dealers advertise their stock on, and their catalogue of vehicles extends to drivers who want to sell a car privately via classified ads.

Autotrader is popular with car buyers because its brand is well-known and trusted by millions of UK motorists.

Search filters allow you to customise your car search by make, model, price, age, mileage, fuel type, economy, and location.

Autotrader recently added car finance and extended warranties to its portfolio of car-buying tools.

Trustpilot reviews: 77,335 | Trustscore: 4.7 out of 5.0

Cazoo is a fast-growing website to buy a used car online finance.

Cazoo (yeah, you can!)

You get excellent benefits from buying a car with an online platform like Cazoo.

Although they falsely claim to offer the best prices (certainly not). We have found many comparative cars advertised for much less than Cazoo prices.

But you’ll get peace of mind with a 7-day money-back guarantee with the assurance that cars have no outstanding finance, theft markers, write-off status or mileage problems.

But a decent vehicle history check from CarVeto’s database is recommended before you buy your next car online.

All their cars are mechanically inspected, and they offer a collection service for a nominal fee.

Trustpilot reviews: 29,847 | Trustscore: 4.7 out of 5.0

Gumtree and eBay are good sites to buy a cheap car online.

Gumtree and eBay

These car-selling platforms favour cheaper cars under the £3,000 bracket.

eBay, in particular, is suitable for buying bangers and non-runners. If you buy a car on eBay, read seller reviews, as it’s easy to get scammed. Avoid paying for a car online and always use PayPal via the eBay cart buying system, as it offers a layer of protection if you run into problems.

Gumtree is a great place to buy a car locally. Rather than buy online, you can view classified listings and call the seller for more information and arrange a viewing.

Use CarVeto to check your next used car before you buy 

With a registration check, run a vehicle through the CarVeto database and check car history. Be on the lookout for outstanding finance, car write off, theft, mileage issues and number plate changes.
