Check the used/for sale forum. Vettehound is another good site to check.
The '01 Z06 was underrated at 385HP; it's pulling close to what the later models are. Plenty of dynos have proven this...
If I was in the market for a used Vette, it would be a low-mileage '01-02 Z06. Anything earlier on a C5, you need to check/ask about oil consumption as there was a head redesign due to oil blowby issues on later models. Didn't effect all Vette's, but it did seem to hit quite a few of them.
