My experience with BMWs is not good. Lots of trouble, lots of cost. I've had this Cadillac CTS-V for 22 months and have put 30,000 miles on it. I have never replaced the tires or had a warranty item. I do use snow tires from November to March and I rotate them at 5,000 mile intervals . My 350Z has been a disaster with tires and radios (3 sets of tires and 3 radios). My car still has no loose anything after 30,000 miles, but it takes some skill to drive this car. It's not for every one.
Big time close ratio transmission and throaty V8 sound.
