That would be a more fair race -- I would expect your M5 to edge it out by slight margin. (Maybe 1-2 cars to 120)Yeah thats what I thought. My dad bought a C55 and I have yet to race him with my 00 M5. I think it would be an interesting race. I have noticed on youtube a lot of races of auto vs manual (ie 300 vs m5) and I really dont think its an even match.
