Moderate sample. 322 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.
This 2012 C180 is a serious reliability red flag: just 6.2% of these cars pass their MOT first time, compared to the UK average of 80%, and the petrol version fares even worse at 0.6%. While dangerous defects are rare at 0%, the sheer scale of failure—with virtually every test requiring work—suggests chronic underlying issues across this cohort.
The median mileage of 79,435 miles is reasonable for a 12-year-old car, yet these vehicles still accumulate 0.1 failures per test on average, indicating persistent mechanical problems unrelated to age alone. If you're considering this model, budget heavily for repairs and get a thorough pre-purchase inspection by a Mercedes specialist; this isn't a car to buy cheaply expecting to save money on maintenance.
The 2012 Mercedes Benz C180 Sport Blueefficiency Auto passes its MOT first time at roughly the UK average rate (83.4%) — solid but worth checking this vehicle's history carefully.
These stats describe 322 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.
