There are better options
 I think you can have a much better car for the same money.  My car has been giving me a lot of headache with the operation of the roof; it stops working without previous notice and not even the BMW guys know why is that. She still is covered by the warranty but my concern is when it's over I'll be the one paying every time this happens again.  Other than that, she runs ok but the engine isn't that amazing considering it's a V8 (should have much more grunts and ponies). Anyway, I wouldn't buy it again. Next time, I'll try Mercedes, Porsche or Audi.
