Is the 200 lbs in the engine or does the body/chassis have some light weight parts? As I recall, the C6 Z06 has a lighter weight carbon fiber front clip instead of fiberglass like the C5s.I think they are $60k or so. 505hp 7.0L naturally aspirated and about 200lbs heavier then a ZR1. When you figure you can get 2 ZR1s for the price of 1 Ferrari and have the same performance, they're a pretty good deal.
