I also left the E39 M5 and now drive a 550i. The only difference is...I cannot give up a shifter with a third pedal. Call me old, call me old fashioned, it just feels right in a car. As far as differences between the two, at the end of the day, I will take the 550i.

No question, 550i Sport is an awesome machine. I must have three pedals though, as God intended it....

 

I think I'm now afraid to drive your car.

How much for an SAT transplant?
