anybody who sits down and thinks about it....507 bhp...V10...i had the privelege of being in one as a co-driver. despite the weight, it handles like a train. just a heavenly car! it's pitty though that there are not (as far as i know) any official bmw tuners who have lightweight projects for those cars. just imagine all this technology in a car with max weight of 1400kg....carbon fiber does wonders...hehe
