Unbelievable car. SMG and iDrive are far better than I anticipated after reading several mixed reviews. Also being previous E39 540 owner. I never really cared for the new E60 5 series design before, the styling on the M5 is stunning. Needless to say I bought the car for it's performance and it has exceeded every expectation. It can ride like a top of the line luxury sedan and with the push of a button, you will feel like you are in a race car ready for the track!
