Other MG models with MOT data
These models have at least 500 recorded tests, but their tested examples do not span enough ages and mileages to rank fairly. Their failure and advisory patterns are still drawn from real tests.

Common questions
- What is the MOT pass rate for MG?
- Across 168,405 recorded MOT tests, 80.8% of MG 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 MG cars most often fail their MOT on?
- The most commonly recorded failure item across MG tests is "Tyre tread depth not in accordance with the requirements", appearing in 12.9% of failed tests. One failed test can list several items, so these shares do not add up to 100%.
- Why do some MG 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 15 MG 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.
