It can be, but only if the individual car backs it up. For the 2015–2018 Mercedes-Benz A-Class 2.1 Diesel Manual W176 facelift, treat model-level patterns as viewing priorities and let condition, history and inspection evidence decide.
The problem cards above list the model-level checks for this guide. Read them as priorities for inspection and paperwork review, not proof that every example will have those faults.

And of course, look at your personalised Should I Buy This Car? report, outlining a full list of common issues in detail, a personalised road test, a plain-English explanation and a MotorIQ score.
