Seen that on Pistonheads i think it was. The DTM's are a rare car indeed. 230bhp, S4 recaro's, alcanta gearknob, handbrake and steering wheel, cabon front and rear splitters and boot spoiler, xenon's etc etc.
I think this one was on pistonheads for about £13k or something similar. Its a bargain for someone who can afford it, as long as the work has been done well, which its seems to have been.
