MB may not be at the bottom but talking to an MB Mech, I know for sure they do get a LOT of business and why I opted for a BMW over an MB.

I don't know what their cutoff number is and that's part of the problem. I wish they'd democratize some of the data - at least show us sample sizes for each model that has a rating.
And my comment is based on common statistical logic. Mercedes has a large lineup, but if you base your aggregate rating on only 2 cars out of their 15+ car lineup - that presents a big likelihood of skeweing of results.
