I've had every part down to the sub frame bushings replaced in my suspension. The car is truly immaculate. It has 108,000 miles on it and lets just say no freeway onramp is wasted with the M5. I don't abuse it but I do drive it spiritedly. I change the oil in it every 4,000 miles and it runs like a top. Planning on having the rod bearings replaced soon however as preventative. I bought this guy's M5 when he traded it in at BMW of SF Some Sterling Gray M5 goodness... ! - BMW M5 Forum and M6 Forums
