Used Car Check
Buying used privately or from a dealer? Check the car before you view it, negotiate smarter, and know when to walk away.
A used car check is about the decision, not just the data
Anyone can pull a list of MOT dates. The hard part of buying a used car is deciding what those dates mean — whether this particular car, at this particular price, is worth your money. That’s the gap AI Reg Check is built to close. The AI Car Check reads available vehicle data. When you supply both current mileage and asking price, the eligible AI Buy Assessment includes an AI Buy Score and “Would I Buy It?”assessment. It is decision support, not a guarantee — the final call and physical inspection are still yours.
Buying privately vs buying from a dealer
The two routes carry different risks, and a good used car check adapts to both.
Private sales
Private buyers get little legal protection, so the responsibility to check falls squarely on you. The seller might still owe money on the car, might not mention a past write-off, or might be optimistic about the mileage. Here the Full Vehicle History Checkearns its keep: it looks for outstanding finance, write-off markers and category, stolen vehicle markers and mileage discrepancies, plus keeper history and any registration changes — shown where available.
Dealer sales
Dealers offer more comeback if something goes wrong, but they also price with a margin and can be persuasive. An independent used car check lets you verify the MOT and mileage story yourself and, using the optional asking-price analysis, judge whether the forecourt price is fair before you start haggling.
What the AI reads for you
- Vehicle details — confirm the spec matches the advert.
- MOT history — advisories, failures and recurring issues that hint at how the car’s been treated.
- Mileage timeline — a steady climb builds trust; odd jumps or plateaus don’t.
- Valuation — an independent estimate to anchor your negotiation.
- Ownership — the number of previous keepers, in context.
- Reliability context — known traits for the model, factored into the score.
A worked example
You find a diesel estate at a dealer for £12,750 and a near-identical one privately for £11,200. Run both. The dealer car shows a spotless MOT record and fair valuation, so the AI leans positive. The private car looks cheaper — until the Full Vehicle History Check flags outstanding finance. Suddenly the “bargain” carries a debt attached to the vehicle, and the cheaper price is no bargain at all. That’s the decision the check exists to inform.
How to use AI Reg Check when buying used
Start free: run the AI Car Check on your shortlist to weed out the obvious no-hopers. When one car rises to the top, run the Full Vehicle History Check before you commit — it’s the step that catches finance, write-offs and clocking. Then, armed with the data and the AI’s verdict, go and see the car in person. No online check can replace turning the key, checking the panels and taking a test drive; treat AI Reg Check as the homework that makes the viewing count.
FREQUENTLY ASKED QUESTIONS
Should I check a used car even if I buy from a dealer?
Yes. A dealer forecourt reduces some risks but not all. An independent used car check confirms the MOT history, mileage and valuation for yourself, and the Full Vehicle History Check surfaces finance, write-off and stolen markers where available.
What is the biggest risk when buying privately?
Private sales carry little consumer protection, so hidden finance, a disguised write-off or a clocked odometer can become your problem. Running a Full Vehicle History Check before you pay is the single most useful safeguard.
Can a used car check replace a mechanical inspection?
No. AI Reg Check is decision support that reads the paperwork and data for you. It cannot see rust under the arches or hear a tired gearbox, so always view, drive and ideally have a car inspected before buying.
How much does it cost to check a used car?
Your first AI Car Check is free, with further AI checks from 99p. The Full Vehicle History Check is £14.95, or £99.99 for a 10-pack if you are comparing several cars.
