How the score works
Every car starts at 100. Each thing a buyer should worry about takes off a published number of points, and every deduction appears on the report with the reason and what to do about it. The result falls into a band: 85 and above is Excellent, 70 to 84 Good, 50 to 69 Fair, 30 to 49 Poor and under 30 High risk.
A score is a summary, not a verdict. Two cars on 80 can have very different reasons, so always read the deductions. The free check scores the car from DVLA and DVSA records, and the full history check rescores it using every check, so the full score is the more complete picture.
What the free score takes off
A mileage reading that went down costs 25 points. No valid MOT costs 12, or 4 if the car is declared off the road with a SORN. Dangerous defects at any MOT in the last three years cost 8. Each advisory or minor defect at the latest MOT costs 1, up to 8. Problems that recur on two or more test days within three years cost 2 each, up to 6. Failing more than half of at least four MOTs costs 4.
An outstanding safety recall costs 6, being marked for export 15 and being untaxed 3. A logbook issued in the last 90 days costs 2. Age costs 2 over 10 years old, or 4 over 15. Averaging more than 15,000 miles a year costs 3.
What the full check adds
The full history check adds the records that matter most. A stolen marker costs 60 points, as does a scrapped marker, and either one caps the score at 10. An insurance write-off costs 50 for Category A or B, 30 for Category S or the old C, and 15 for Category N or the old D, or 25 if no category is recorded. Outstanding finance costs 30 and a high-risk marker 25.
Being recorded as exported costs 10. Six or more previous keepers cost 6, and four or five cost 3. An imported car loses 3. More than two plate changes cost 2, and so does a change of colour.
What costs nothing
Some things are shown for information only: consistent mileage, not enough readings yet, a valid MOT, a car too new for its first MOT, a SORN tax status, a normal number of keepers, and a clear finance, write-off or stolen record. They tell you what is right with the car, which matters just as much.
The score never replaces a proper look at the car. Use it to rank a shortlist, then inspect the best with our test drive and inspection checklist. You can see every deduction laid out in the sample report.
