About these figures
- They cover every Grand C4 version DVSA records under this name (engines, trims and generations together), on its first MOT test of each visit. A “pass with rectification” (fixed within an hour) counts as a fail, as in DVSA’s own statistics.
- Cars under three years old are left out, because the few tested that young are mostly taxis.
- Fuel mix of the cars tested: diesel 93.4%, petrol 6.6%.
- A pass rate describes the model, not any one car. How a car has been looked after matters more.
