Pass rate by year
Click any year to see full MOT history, common faults and comparisons for those cars. Verdicts are relative to this model's own average — a good Land Rover year is judged differently from a good Toyota year.
How is this measured?
What "pass rate" means
The percentage of all MOT tests that resulted in a pass — counted across a car's whole life, not just its first test. Higher means fewer failures over time.
Mileage groups built from real data
We split this model's real-world mileage history into 5 equal groups — so each slice contains the same number of cars, not an arbitrary round number like "0–30,000 miles."
Does age still matter?
Yes. A low-mileage 20-year-old car has still had 20 years of weather, perishing rubber, and ageing electrics. Comparing at the same mileage narrows the gap between old and new — but doesn't erase it entirely.
Why this beats surveys
Our figures come from the DVLA's national MOT database — over 50 million real test results from accredited garages, with no opinions involved. Most reliability guides are based on owner surveys with a few hundred responses per model.
