That is a GTD R42 (this yellow one owned by GTD club member Dave Parker). There are not many of them out there I think it is either 19 or 26 all in. Others know more than me on this subject but they are quite competent cars! I think that the project ended up with Saleen via a convoluted route of owners but again I think others know more than me on this. Most are road cars but Dave's is more competition orientated than road going. In fact it is a beast of a car. I competed in Ray Christophers own R42 in a sprint at Curborough when my 40 blew its clutch, and it really flew. With me driving it also flew right off the road but no harm done! I arrived at the corner much quicker than expected so didn't make it. But if I had, it would have been a winning time......naturally!
