I've had this 550i for about a year, the car is awesome. Very fun to drive, turns heads (especially those people who rev up their engines in their G35 or the equivalent). Reliability - not so good. In 1 year I went through 5 tires and 2 cracked rims. Note I do live in New York City where the roads are NOT the best but before this I had a Lexus LS430 since 2001 and I only went through 1 tire so do the math.
SPEEEED! ACCELERATION! I-Drive! and the whole interior + exterior
Cupholders are awful. They're made to be broken at which point you crazy clue those bad boys back into place. Tires - RFT is the only plausible solution? Rims - why are they so weak on this years 5 series?
