Buying a Car on eBay Motors UK: Check Guide (2026)

Short answer: Before bidding on or buying any car on eBay Motors, enter the registration plate on CarCostCheck for a free MOT history, mileage, and reliability check. If the car passes, pay £4.99 for the premium report to check finance, stolen, and write-off status. eBay bids are legally binding, so check first and bid second.

eBay Motors: What You Need to Know

eBay Motors is one of the UK's best-known online car marketplaces. It offers both auction-style bidding and Buy It Now fixed prices, from both private sellers and dealers. Its feedback system gives you more to go on than Facebook Marketplace or Gumtree, but eBay offers no purchase protection for cars bought on its UK site.

The eBay Car Check Process

Step 1: Get the Reg from the Listing

Most eBay car listings show the registration plate in at least one photo. If the plate is blurred or hidden, ask the seller via eBay Messages before bidding. A seller who will not share the reg before you commit to buying is a red flag.

Step 2: Free Check (30 seconds)

Enter the plate on CarCostCheck. Compare the free report against the eBay listing:

• Does the mileage match? Check the last MOT reading against the listing claim.
• Does the year, colour, and engine size match?
• What is the MOT history like? Any serious failures or recurring advisories?
• What are the running costs? Do they fit your budget?

Step 3: Premium Check (£4.99)

If the free check is clean and you want to bid, run the premium report. This is critical because eBay auction bids are legally binding. You do not want to win a car only to discover it has £10,000 of PCP finance on it.

Step 4: Check the Seller

• Review their eBay feedback score and read recent reviews
• Check if they have sold other cars recently (possible trader posing as private)
• Verify their location is consistent with where the car is listed

eBay Vehicle Purchase Protection: Not Available in the UK

Many buyers assume eBay protects car purchases. On eBay.co.uk it does not. eBay's UK safety advice says it does not offer Vehicle Purchase Protection, its Money Back Guarantee, or refunds for vehicles bought on the UK site. Vehicle Purchase Protection only covers buyers on eBay's US and Canadian sites.

That has two practical consequences:

• Treat any "eBay protection" claim as a warning sign. eBay warns that a seller who says a UK car sale is covered by eBay protection, a refund scheme, or an eBay escrow or holding account is likely a fraudster. eBay does not offer escrow.
• Your own checks are your protection. If the car turns out to have outstanding finance, a write-off record, or a mileage problem, eBay will not refund you. Buying from a dealer on eBay still gives you your Consumer Rights Act rights against the dealer, but a private sale does not.

Running your own car check for £4.99 before bidding is the simplest way to protect yourself.

eBay Auction vs Buy It Now

Factor	Auction	Buy It Now
Potential savings	Higher (can win below market value)	Fixed (sometimes negotiate via "Make Offer")
Risk	Higher (bids are binding, emotional bidding)	Lower (time to think)
Time pressure	High (auction end time)	Low
Car check timing	Must check BEFORE bidding	Can check before paying

If you are buying at auction, run all checks before placing your first bid. Set a maximum bid based on your research (including the CarCostCheck running cost and reliability data) and do not exceed it.

What Makes CarCostCheck Different

CarCostCheck is not just a cheaper version of HPI. As well as the history check, it helps you judge whether a car will be a good one to own. Here is what you get that HPI does not offer at any price:

• Market valuation from £2.99, based on live UK dealer listings. See the local dealer value for your car and how quickly similar cars sell near you.
• Estimated vehicle lifespan: An estimate of how many years the car has left on UK roads and the probability of it still being on the road in 12 months.
• Insurance costs by age: See estimated annual premiums for drivers aged 20, 30, 40, and 50. Budget before you buy.
• Running cost breakdown: Annual fuel, road tax, MOT, predicted repairs, and total cost per month. All calculated for this specific car.
• Reliability score (0-100): one number based on the car's MOT record, including its pass rate, recent failures, advisory trend and mileage. Free.
• Common faults: the problems that keep coming up in the car's own MOT history. Free.
• 12 free checks: Full MOT history, mileage verification, reliability score, running costs, fuel costs, red flag alerts, common faults, recall check, ULEZ compliance, tax and MOT status, and more. All before you pay a penny.

The premium history check (£4.99) uses the same Experian database as HPI, AA, and RAC. You get the same core checks: stolen, outstanding finance and write-off. The complete bundle (history + valuation) is £6.99, still 65% cheaper than HPI's basic check.
