Most-tested cars
Frequently asked questions
How accurate is this?
It shows how cars like yours did at the NCT in 2025, from RSA data on initial tests. It cannot see your car: maintenance, mileage and condition matter more than the averages.
Where does the data come from?
The RSA 2025 Make and Model Data, which covers 1,725,291 initial NCT tests. Models with fewer than 2,000 tests and model-years with fewer than 100 are not shown.
My car is not in the list. What can I do?
Smaller models are grouped out by the RSA for data protection. Use the pass rate for your year of car in pass rate by car age, and go through the checklist.
