Got a specific BMW 420d M Sport MHEV Auto you're checking out?

The real detail is in the individual vehicle report — MOT history, AI Hunches, mileage timeline, and defect patterns for that specific reg.

This 2023 BMW 420D is running well above the UK average, with a 95.8% first-time pass rate compared to the national 80%, and dangerous defects are rare at just 1.1% of vehicles tested. It's a genuinely reliable performer so far, with almost no failures (0.01 per vehicle) and zero advisories on average.
