Hi NS, I did a search on this previously, a lot on the 635 Group A, but nothing on the M3, which really does surprise me! I will wait to see what records BMW can give us, and post them up, if nothing then I will start a thread on the chassis history archive, and get a list going.It seems ironic that the most successful car in touring car history seems to be the least documented- or am I just not looking in the right place?!!!
