Can i just say sell your Cosworth's & buy an M5, i've had 4 Cossie's over a 10yr period & been out of them for over 2yrs now, i have no desire whatsoever to own another Cosworth as much as i like them. Get an E39 M5 you won't regret it & it will probably work out cheaper than owning/running a Cossie in the long run !
