I must say even with the problems that I have had with my 540i, it still is a pleasure to drive. I am a little disappointed with BMW because over the past years of ownership I have had to replace Sunroof Tilt, control arms, radiator, wheel bearing, instument panel. It is an expensive car to run there no questioning that. That why I have a Honda. The quality of the car is excellent but the reliability could be better. I have never been stranded anywhere but there have ben tedious moments with my 540i. The performance on the car is AMAZING. You get pushed back into you Seat on full trotle takeoffs. The feeling is great. Its like having an f-16.
Engine, 5 speed auto slickly smoothness, Instument Panel (after I paid 700 to ge tit fixed)
Cupholders, radio really sucks. Dealers treat you as if you have money to through around.
