Buying a used car online is now the default for millions of UK buyers. It's faster, the choice is wider, and you can shop in your pyjamas. But scams and dodgy cars are very real — and the second you transfer money is the moment you have least leverage.
The Three Categories of Online Car Selling
Before you spend a penny, understand who you're actually buying from. There are three types:
- Direct online retailers (Cazoo, Cinch). They own the car. Most consumer-protective.
- Dealer marketplaces (AutoTrader, Motors.co.uk). Mostly franchise and independent dealers. Solid consumer rights apply.
- Private/auction marketplaces (eBay Motors UK, Facebook Marketplace, Gumtree). Can be cheapest, but consumer protection is essentially nil.
Five Checks You Must Do Before Buying
1. Run an HPI Check
This is non-negotiable. An HPI check (£20–£30) tells you if the car has outstanding finance, has been written off, has a mileage discrepancy, or has been reported stolen. Without this, you're gambling.
2. Verify the MOT History (Free)
Visit gov.uk/check-mot-history. Type in the registration. You'll see every MOT the car has ever had — including failures, advisories, and recorded mileages at each test. If the mileage doesn't match, walk away.
3. Check the Seller's Identity
Their name and address on the V5C log book must match what they tell you. If anything seems off, abandon the deal.
4. View the Car in Person (Or Buy from a Returns-Friendly Retailer)
If buying privately, you absolutely must see the car. If buying from Cazoo or Cinch, the 7-day return policy serves the same protective function.
5. Never Pay by Bank Transfer to a Private Seller
This is the single most common UK car scam. Payment goes through, "seller" disappears, the car was never theirs. Use PayPal Goods & Services, or pay in person on collection. Bank transfer = zero protection.
The Top Scams to Watch For
- Too-good-to-be-true prices on Facebook Marketplace or Gumtree. The seller is "abroad" and wants payment via "eBay's secure system" (which doesn't exist for cars).
- Cloned vehicles — the registration plate is genuine, but it's been copied onto a stolen car.
- Outstanding finance — the seller doesn't legally own the car. The finance company can repossess it from you.
- Clocked mileage — speedometer reading rolled back. MOT history will reveal this.
Your Consumer Rights
From a UK dealer, you have rights under the Consumer Rights Act 2015. Cars must be of satisfactory quality, fit for purpose, and as described. You can reject a faulty car within 30 days for a full refund.
From a private seller, your only legal protection is "the car must match the description given." That's a much weaker right and far harder to enforce.
The Bottom Line
Online car buying is safe — if you stick to legitimate platforms, do the basic checks, and never pay before you can verify the car. Use Car Cupid to compare across multiple trusted sites in one place, and you'll keep your search both efficient and safe.
