CHris Harris sums it up pretty well. While the Ford has ergonomics of a truck and stone aged solid axle that can't handle bumps it's fun as hell. The Chevy is more refined and boring. Too bad Chevy detuned the motor. But then if you did a simple reflash with better tune I suspect you could grab extra ponies from the ZL1 and actually use that extra power.

I can't see myself in either car. I'd buy a used Porsche 911 turbo and mod it if I wanted something insanely fast for $50K.pretty easy to bolt GT3 suspension on 911 and make simple tweaks to turbo tune to extract 600 hp.
