Deal check · is it worth buying?
What is a deal check?
A history check tells you the car's past. A deal check tells you whether the listing in front of you is actually worth buying at the price. It reads the advert, benchmarks the asking price against the market, reads the MOT and mileage story, and gives you one clear verdict: buy, negotiate, or walk away. It is the half of buying a used car that no reg lookup covers, and it is where most people lose money.
Two different questions
Buying a used car well means answering two separate questions. Most buyers only pay for the first one.
"Has this car got a clean record?"
Outstanding finance, insurance write-off, stolen and scrapped markers, mileage records. The car's past, from licensed data. Essential, but it stops there.
"Is this one worth buying, at this price?"
The advert, the asking price against the market, the MOT and mileage story, and a straight verdict. The part a data report leaves wide open.
What a deal check looks at
Four things, weighed together, to answer one question: should I buy this one?
The price vs the market
The asking price benchmarked against similar cars selling right now, so you know if it is fair, high, or too good to be true.
The actual advert
The wording, the photos and the seller signals worth questioning, not just the DVLA record.
The MOT and mileage story
Advisories that keep coming back and mileage that does not add up, read from full DVSA history.
A clear verdict
Buy, negotiate, or walk away, with a deal score out of 100, not a table of raw data to interpret yourself.
What each check answers
A history check and a deal check are not rivals. They answer different questions, and a careful buyer wants both.
| History check | Deal check | |
|---|---|---|
| Is the car clear of finance, write-off and theft? | – | |
| Is the mileage genuine? | ||
| Is the asking price fair? | – | |
| Does the advert and seller add up? | – | |
| What should I negotiate, and from what figure? | – | |
| Should I actually buy this one? | – |
Want both in one report? A Full Buyer Check runs the history and the deal check together.
The deal score, explained
Every listing gets a score from 0 to 100, so the verdict is a straight call, not a hunch.
Fairly priced, records stack up, nothing that should stop you. Worth viewing.
Something needs a closer look, price, history, or a gap in the story. Worth a question before the trip.
The price, the records or the advert throw up a real problem. Usually a walk away.
Run one in 60 seconds
You do not need the seller, a test drive, or even the listing URL to run a deal check. Screenshot the advert, or drop in the reg, and CarMate reads the price, the advert, the MOT and mileage, and hands you a deal score and a verdict before you message anyone. A Listing Check is 1 credit (£5.99), and your first credit is free when you sign up. Add the recorded history for the full picture with a Full Buyer Check.
Deal check FAQs
What is a deal check on a used car?
A deal check answers one question: is this specific car a good buy at this price? It reads the actual advert, compares the asking price to similar cars selling now, reads the MOT and mileage story, and gives a clear verdict, buy, negotiate, or walk away. It is about the deal, not just the car's record.
Is a deal check the same as a history check or HPI check?
No. A history check (or HPI check) tells you the car's past: outstanding finance, write-off, stolen markers and mileage. A deal check tells you whether the listing in front of you is worth buying at the price. They answer different questions, and a serious buyer wants both. CarMate can do each, or combine them.
Does a history check tell you if the price is fair?
No. A history check confirms the car has not been written off, stolen or left on finance, but it says nothing about whether you are overpaying, whether the advert adds up, or whether it is worth the trip. That is the gap a deal check fills, and it is where most buyers lose money.
How do I know if a used car is a good deal?
Compare the asking price to similar cars selling now, check the MOT history for repeat faults or mileage that does not add up, make sure the advert and seller are consistent, and confirm the recorded history is clean. A CarMate deal check does all four from a screenshot or the reg and gives one plain verdict.
What is a good deal score?
CarMate scores every listing from 0 to 100. A score of 67 or above is a Good Deal, 34 to 66 means Proceed with Caution, and below 34 is Not Recommended. The score weighs the asking price against the market, the MOT and mileage story, and any fraud or scam signals in the advert.
Can you check if a used car is overpriced?
Yes. A deal check benchmarks the asking price against comparable cars selling right now, so you can see whether a listing is priced fairly, sitting above the market, or suspiciously cheap. It also gives you a real, data-backed figure to negotiate from instead of guessing.
