^^good info, thanks . I am not looking for a M5 that i can pick up for cheap since it's beat to hell or might need work. I know it's gonna haunt me. If i am picking up a such car i will make sure it's in good condition and it's taken care off. I know mods for the M5's are pretty penny. On headers/exhaust i am gonna experiment first and gonna try a custom exhaust (making up mind which muffler i want to go with...Miltek sounds pretty good). Don't know how wide dinan headers are(?), but if i can i am going to have some fabricated with 2.25" diameter (bigger if possible, gonna loose bit mid power, but gain hell of a lot top end). Then the basic bolt ons. M5 will be a over all car, for straights and turn.

With the MB's I'll be looking for....only straight line and luxury. e55 can be killers if done right with mods. Same for the S-Type R, gonna upgrade the pully, port the blower, exhaust, bolt ons. It has the same blower as Land Rover Sport so there are few mods out for it. Looks like SVC has a nice package for it, which includes software and removes the speed governor lol.

LS400 (98-00), i simply love that shape. That car by no means will be for speed, just crusing. Gonna give it a very mean roar tho. Same applies for the 740.
