Best Used Car Websites in the UK (Buying vs Selling Explained)
Buying or selling a used car online is easier than ever, but not all car websites do the same job. Some are best for buying, others are geared towards selling, and a few are really only useful as a price check.
This guide explains which used car websites in the UK are actually worth using, what each one is best for, and when it makes sense to look elsewhere. I’ve also linked out to my deeper reviews where it matters, so you don’t have to guess.
Quick comparison: which used car website should you use?
Website | Best for | Buy or sell | My take |
|---|---|---|---|
Biggest choice | Buy & sell | Best place to start | |
Delivered cars | Buy | Convenient, but pricier | |
Dealer stock | Buy | Good warranties, limited choice | |
Best selling price | Sell | Dealers bid for your car | |
Speed | Sell | Fast, but fees apply | |
No fees | Buy & sell | Cheap, but higher risk |
Best used car websites if you’re buying
AutoTrader
⭐ 4.5 / 5 — Best place to start if you’re buying
AutoTrader remains the go-to site for buying a used car in the UK. It has by far the biggest selection, covering dealers and private sellers.
It’s excellent for research, price comparisons, and filtering by spec, budget, or running costs. You can also sell privately here, but listings aren’t free.
Why AutoTrader works
✅ Massive choice of cars
✅ Excellent search and filters
✅ Strong pricing data
Where it falls short
❌ Private listings come with fees
❌ You still deal with sellers directly
Cinch
⭐ 4.1 / 5 — Best for hassle-free buying
Cinch is all about convenience. Cars are bought online and delivered to your door, with a 14-day money-back guarantee.
You’ll usually pay more than buying directly from a dealer, but if you value ease over price, that trade-off can be worth it.
Why Cinch works
✅ Buy entirely online
✅ Home delivery included
✅ 14-day return window
Where it falls short
❌ Prices are often higher
❌ Limited negotiation
Sytner Select
⭐ 4.2 / 5 — Best for approved used cars from main dealers
Sytner Select is the used-car arm of the Sytner Group, one of the UK’s largest dealer networks. Cars are typically ex-demo, approved used, or part-exchanges from Sytner dealerships.
You’ll usually pay more than you would buying privately, but cars come with proper checks, warranties, and the reassurance of dealing with a large, established dealer group.
Why Sytner Select works
✅ Approved used cars from main dealers
✅ Warranties and inspections included
✅ Backed by one of the UK’s biggest dealer groups
Where it falls short
❌ Prices are higher than private sales
❌ Less flexibility on negotiation
Useful for price checks (but not final decisions)
You’ll also come across sites like CarGurus, Motors.co.uk, and Carsnip when searching for used cars.
These sites mainly act as aggregators, pulling listings from dealers rather than offering a buying experience themselves. They can be useful for checking whether a price looks reasonable, but they’re rarely the best place to actually complete a purchase.
For most people, AutoTrader does this job better, with more listings, stronger filters, and clearer pricing data.
Best used car websites if you’re selling
Motorway
⭐ 4.5 / 5 — Best overall price without selling privately
Motorway is the platform I recommend most often for selling.
Instead of giving you a fixed price, it shows your car to thousands of dealers who bid against each other. That competition is why prices often beat instant-offer sites.
You upload details and photos from home, accept the best bid, and the dealer collects your car. Listing your car is free to.
Why Motorway works
✅ Dealers bid against each other for your car
✅ Easy to use
✅ Sell entirely from home
Where it falls short
❌ Not always the fastest option
❌ Seller fees have been introduced
❌ Collection can take a few days
We Buy Any Car
⭐ 3.1 / 5 — Fastest way to sell, not the best price
We Buy Any Car is built for speed. You can sell your car within hours — but that convenience often comes with deductions and fees.
Initial online valuations are usually optimistic, cosmetic damage is penalised heavily, and transaction fees apply to most sales. I’d use it as a benchmark rather than a final decision.
Why We Buy Any Car works
✅ Very fast sale (often same day)
✅ Simple, familiar process
✅ Nationwide coverage
Where it falls short
❌ Initial valuations often reduced
❌ Multiple transaction and payment fees
❌ Final price can be far lower than expected
Facebook Marketplace
⭐ 3.6 / 5 — Best for fee-free private buying and selling
Facebook Marketplace can work well if you’re confident, patient, and know what you’re looking for. I’d use it for cheaper cars where fees would eat into the value, but I wouldn’t rely on it for higher-value vehicles without proper checks.
It’s best treated as a budget option, not a polished buying experience.
Why Facebook works
✅ No listing fees for sellers
✅ Huge local audience
✅ Useful for cheaper, older or runaround cars
Where it falls short
❌ High number of time-wasters
❌ No buyer or seller protection
❌ Scams and misdescribed cars do exist
Sites like eBay Motors and Gumtree work in a similar way, but both come with trade-offs. eBay involves listing fees, while Gumtree has become increasingly hit-and-miss, with a higher risk of scams and poorly described cars.
If you’re selling privately, Facebook Marketplace is usually the simplest option. But it still requires caution, especially for higher-value vehicles.
Which used car website should you use?
- Best overall for buying: AutoTrader
- Safest dealer buying: Sytner Select
- Easiest buying experience: Cinch
- Best selling price: Motorway
- Fastest sale: We Buy Any Car
- Cheapest private option: Facebook Marketplace
If you’re selling and price matters, don’t stop at one quote. Running your car through Motorway and We Buy Any Car alone can easily mean hundreds of pounds difference.
Final thought
There isn’t one “best” used car website… only the best one for what you’re trying to do.
Use buying sites to research.
Use selling sites to compare prices.
And don’t confuse speed with value.
If you do that, you’ll avoid most of the expensive mistakes people make when buying or selling a car online.

Frequently asked questions
What is the best used car website in the UK?
There isn’t one single “best” site for everyone. AutoTrader is usually the best place to start if you’re buying due to its huge choice and strong pricing data. If you’re selling, platforms like Motorway and We Buy Any Car are more relevant, but they serve very different needs.
What’s the best website to sell a car quickly?
If speed is your priority, We Buy Any Car is usually the fastest option, often completing sales the same day. The trade-off is price, as valuations are often reduced and fees apply. If you want a better price and can wait a few days, Motorway is usually the stronger option.
Do car buying websites give lower prices than selling privately?
In most cases, yes. Private sales typically achieve the highest price because there’s no middleman. However, they also come with more hassle, time-wasters, and risk. Car buying websites trade some value for convenience and speed.
Are sites like CarGurus or Motors.co.uk worth using?
They can be useful for price checks, but they’re rarely the best place to complete a purchase. These sites act mainly as aggregators, pulling in dealer listings. For most buyers, AutoTrader offers the same benefits with more depth and better filters.
Is Facebook Marketplace safe for buying or selling cars?
It can be, but it comes with higher risk. There are no fees, which makes it popular for cheaper cars, but there’s also no buyer or seller protection. Scams and poorly described cars do exist, so extra caution is essential, especially for higher-value vehicles.
Should I get more than one valuation before selling my car?
Yes, always. Running your car through at least two platforms can make a significant difference. Comparing Motorway and We Buy Any Car alone can often mean hundreds of pounds either way.
