Moderate sample. 316 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.
The 2016 BMW 420D M Sport is significantly less reliable than the UK average, with a first-time MOT pass rate of just 54.1% compared to the national benchmark of 80%—this is a major red flag for a potential buyer. No dangerous defects have been recorded in the sample, which is the one bright spot in an otherwise concerning reliability picture.
At around 70,000 miles these cars aren't particularly high-mileage for their age, yet they're still failing MOTs at nearly twice the typical rate, suggesting inherent durability issues rather than wear-and-tear problems. Before committing to a purchase, arrange a comprehensive pre-buy inspection from a BMW specialist, as the generic MOT pass rate here indicates you'll likely face significant repair costs beyond routine maintenance.
The 2016 BMW 420d M Sport Auto passes its MOT first time more often than most UK vehicles (96% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
These stats describe 316 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
