- What is the MOT pass rate for Caterham?
- Across 1,106 recorded MOT tests, 87.7% of Caterham tests ended in a pass, against a national average of 72.3%. A make-level figure blends very different cars, so the individual model pages are the more useful comparison.
- What do Caterham cars most often fail their MOT on?
- The most commonly recorded failure item across Caterham tests is "Lambda coefficient outside the default limits or the range specified by the manufacturer", appearing in 12.3% of failed tests. One failed test can list several items, so these shares do not add up to 100%.
- Why do some Caterham models not have a pass rate ranking?
- A model is only ranked when its tested examples cover a wide enough spread of ages and mileages for a fair comparison. 0 of the 1 Caterham models here qualify. For the rest we publish the unadjusted rate and the failure patterns, but not a rank, because comparing unadjusted rates mostly sorts cars by how new they are.
How to read these figures
Why the adjusted rate is the fair one
An unadjusted pass rate is strongly driven by the age and mileage of the cars being tested, not by how well they were built. A model bought mainly as a lightly used second car will look better than an identical car sold to high-mileage drivers. Adjusting for age and mileage compares each model against cars that have lived a similar life.
For a specific car, its own record beats any model average — check that vehicle’s MOT history and read what testers actually recorded against it.
