Either of the ZR1's are very nice ride be it the high reving C4 version or the new Supercharged beast.
I was looking at the C4 version before deciding to purchase a newer C5, I liked the idea of the high
rev dual overhead cam engine but was not sure about who would be able to modify the car or actually
be able to repair it if needed other then the dealer at that time. (before I knew of Manny@ECP)
You can turn an already powerfull engine into a real screamer with a few mods, cam, headers, tune etc
and get a good deal on the older C4 south of the boarder with our dollar flying high and at par right now.
