When it comes to reliability I think the German cars are more model specific. Unlike Lexus where pretty much everything is nearly bulletproof or Chrysler/Jeep where almost everything isn't, reliability among the German offerings seems to vary. Look at my ML. I know a guy with a 2010 gas ML that has had zero issues.(Of course he doesn't have diesel emissions controls, Blind Spot or Parktronic....those are the things that have accounted for 90% of my issues) Or take BMW. The 3 series rates above average reliability while the 7 series is a nightmare by all accounts.
