There you go - I trusted the Honda part of my dealer, but my Honda had a bunch of problems under warranty, didn't cost me, but made me ask why not drive something more interesting, and there were BMW, Mercedes, and Mini under the same ownership, next door. So I thought, eh, the difference in reliability is exaggerated, I'll get a used German car for peanuts, considering the extreme depreciation, and be dealing with the same people. I don't regret buying an out-of-warranty car (yet), but I didn't realize that once they assessed me as someone who makes poor decisions/is reckless/has too much money that they would not treat me the same as with the Honda. Or maybe it's just separate management.

So I conclude, as everyone says, you got to do your own work as much as possible on an out of warranty European car.
