Great car bought it from a friend who upgraded to the M5 with the SmG. Has all options except heads up display. She now misses her 550i and I love it. Acceleration is smooth but stupidly fast. Can do 120 and not even break a sweat. Fuel economy is around 17 for city, but 27 for highway doing 80. Impressive. Love the interior, 20 way comfort are great. Idrive is useful I think older people just get confused with new technology (I'm 24). Can be finicky at times however. The styling works for the car depending on the color. Mines black with tan interior so it looks understated and all business. Keep making excuses to go drive somewhere. Car is so much fun.
Instant V8 power, seats, harman kardon sound with 13 speakers, surprising large trunk, quietness.
fuel economy could be better (improved for 2011 models), cup holders are retarded, get rid of the run flat tires (replaced them with Michelens). Climate control in the Idrive is a pain to use sometimes.
