My problem with this car - and with the 3.8 RS - is that they are trying to serve a dual pupose, namely being a road car but great on the track. No use. You cannot have both.
My RS is great on the track, truly amazing, now after 2 track days and alignment I can say the step from the M3 on the track is as large as the step to the M3 from a Audi A4. But, and here is a big but the car is not good as a road car, just isn't. So I am thinking right now - and I thought about the new 4.0 RS too and dismissed- to get the Cup S or a Radical SR8. No reason to go halfway. (my prior reason was not to have a trailer)
