Opel NCT questions
What is the Opel NCT pass rate?
In 2025, 47.7% of Opel cars passed the NCT at the first attempt (26,206 of 54,979 initial tests), compared with 49.3% for all cars.
Which Opel model has the best NCT pass rate?
Among Opel models with at least 2,000 tests, the Corsa did best (47.5%). Remember that newer models are usually younger cars, which pass more often.
Does the make of a car decide whether it passes?
Not on its own. Age, mileage and maintenance matter more, and the RSA warns its figures do not account for them. Use these numbers to know what to check, not to predict a result.
