Is it Movit owner, Guido Frensemeyer's car you are refering to? He has a red ZR1 with a 527 big block in it!!

Before that he had a black ZR1 with a Jeal 368 that has been owned by Joe in the UK for ages. It is a quick car. I've heard there is currently some youtube footage of it driving at 200 mph on the road.
