I love the ZR-1...but DAMN was that an expensive car. It was almost $70,000 in 1995(?) when they discontinued it, when a Supra cost $50,000 and a 911 Carrera cost about $60,000. But, man, oh man, talk about an
engine...wonderful car.
If offered either car, I would take the ZR-1 over the Z06 just because its so understated for its performance, and I like the ZR-1's looks over the Z06. However, if it was my money, definitely Z06, easier to mod, and work on.
