Should I check the MOT history before buying a 2012 Mercedes Benz Ml350 Sport Bluetec Auto?

This 2012 ML350 is a significant reliability concern: only 37.8% pass their MOT first time, less than half the UK average of 80%. The good news is that dangerous defects are virtually absent from this cohort, but the sheer frequency of failures means you're looking at regular repair bills.

At around 100,500 miles on the clock, these cars have covered typical mileage for their age, yet they're still generating an average of 0.34 failures per vehicle — suggesting wear-related issues are catching up fast. Before buying one, budget for immediate remedial work and factor in ongoing maintenance costs, as this model clearly doesn't age gracefully.
