This 2018 BMW M140i Shadow Edition has a first-time MOT pass rate of just 30.8%, less than half the UK average of 80%, which is a serious red flag for potential buyers. Petrol models show a 0% pass rate in this dataset, though the dangerous defect rate is reassuringly low at 0%, suggesting problems tend to be fixable rather than safety-critical.
At 39,708 miles average, these cars are well-used for their age, and while the 0.02 failures per vehicle and zero advisories per vehicle indicate they're not generating major issues once they do pass, the extremely low first-time pass rate suggests owners are dealing with repeated test failures before getting through. Before committing to purchase, have a pre-buy inspection done by a BMW specialist and ask the seller for its full MOT history—the pattern of what's failing will tell you whether it's worth the hassle.
