The plate doesn’t change. The decision framework does.
You’ve already found a car — or you’re about to. The question isn’t only whether the record looks clean. It’s whether this deal works the way you’re buying it: under the hammer, on a dealer forecourt, or from a private seller. Same registration. Different risk, rights, and next step.
If you’re still building the listing-first habit (paste, Free→Basic→Premium, buy/hold/walk), start with How to check if a used car listing is a good buy (UK). This guide zooms in on channel. Paste the listing, registration, or VIN into UseRalph when you’re ready to run it for real. Want the shape of a finished report? Open the sample report.
Why channel changes the verdict
Listing context beats “reg only.” Price, photos, seller wording, and how you’re buying change what “good buy” means. A private hold can become an auction walk once fees, transport, and repair exposure are counted. A dealer “buy” framing still sits under consumer law you won’t get in a private sale.
Ralph’s job is a verdict on this listing for this channel — not a generic health score. Free still filters identity, MOT, and mileage. Free does not clear outstanding finance, stolen markers, or insurance write-offs. Basic (8 credits) adds the full public-record verdict and previous adverts when available. Premium (25 credits, £9.99 pack framing on the homepage) adds licensed finance, stolen, and write-off markers, valuation, and price or bid guidance before money moves. Vehicle history data is licensed from third-party providers, including data provided by Experian. See Ralph’s Terms for what that data does and does not cover.
Auction: evidence without a test drive
You usually can’t test drive. Evidence is the lot description, photos, history, and what you can infer about fees and repairs. Supported auction links on Ralph’s homepage include Copart and IAA/SYNETIQ. If a link can’t be extracted, enter the registration or VIN plus the key claims and still run the check.
Ralph’s auction mode weighs those inputs and guides a safe maximum bid: the most you can pay once costs are counted and the numbers still work. Fold in buyer’s fees, transport, and likely repairs. If the lot only works below a line you won’t win at, that’s a walk before the hammer, not after.
“Ralph spots details I miss when I review auction lots manually, and those details keep proving important.” — auction buyer (homepage)
Treat Premium as the layer before a serious bid. Finance, stolen, and write-off markers matter as much at auction as they do on a forecourt — and you have less room to unwind a bad purchase after the hammer falls. An online “buy” framing still isn’t a mechanical inspection. Photos miss hidden damage. If the lot description and the record disagree in ways that kill the economics, walk.
Dealer: advert vs record, then your rights
Compare the advert to the record: mileage claims, condition language, service story, and valuation. Ralph surfaces negotiating points and a clear next step — buy, hold for answers, or walk. Previous adverts (Basic) often expose a different price, damage note, or mileage story from last month’s listing of the same car.
Purchases from dealers sit under the Consumer Rights Act. Goods should be of satisfactory quality, as described, and fit for purpose. For rights detail and how to escalate, use Citizens Advice on buying a used car. Don’t treat any tool as a substitute for that advice.
A clean MOT history isn’t enough to pay a deposit. Run Free first via GOV.UK’s MOT history check or Ralph’s free layer, then Basic on the shortlist, then Premium on the one car you’re about to buy. Official buying steps also live on GOV.UK’s checks when buying a used car.
Private: fewer protections, more “hold until proven”
Private sales carry fewer legal protections than a dealer sale. Ralph’s private mode checks the seller’s story against the record, flags missing evidence, and tells you what to ask and verify before paying. Expect more “hold until X is proven” outcomes: V5C in the seller’s name, consistent keepers, and claims that survive previous adverts.
Again, Citizens Advice is the place for rights and payment caution. Ralph’s job is the listing-versus-record verdict — not legal advice, and not a substitute for seeing the car.
Walk early on free evidence when mileage goes the wrong way, identity doesn’t line up, or the MOT trail can’t absorb the “one careful owner” wording. Save Basic and Premium for cars that still deserve travel and a deposit conversation.

After the channel verdict: still view the car
Whatever the channel, an online verdict isn’t the final check. Match the V5C and VIN, view in daylight, test drive when the channel allows it, and book an independent inspection when stakes are high. For the full viewing ritual and walk-away rules — including why you can walk even after a Premium “buy” framing — see After the online car check — viewing and walk-away rules (UK).
Ralph can’t replace a mechanical inspection. Records and photos miss hidden damage. The report is evidence for a decision. The car in front of you is still the last word.
