When deciding to buy a Mercedes car, you might want to consider its reliability rating. A dependable Mercedes model is the one that runs for years without posing any major trouble. Since that doesn’t have to hit the workshop most often, it won’t cost you an arm and a leg for repairs. The question is, how do we know which are the most reliable Mercedes cars?
Well, for that, we need to consider the dependability ratings of J.D. Power and U.S. News. Both organizations release their rankings every year while taking into account replies from thousands of verified Mercedes owners and the issues they report. The fewer are the issues, the more dependable is the Mercedes model.
The US. News also considers critics’ rating, performance, interior, and safety attributes to create their overall USN score. They rate each attribute on a scale of a maximum of 10.
