if you only have $200K to shell out.....The dealers I talked to that are getting them are doing major mark up - since people are willing to pay it.
I'll do you a favor, because I'm Camaro Scotty! Buy my 2008 Z06, We'll send it out to Lingenfelter for the engine build....get your 630 hp WITHOUT a supercharger, and still be at about $80K
You COULD, of course, get the best build for $44K, and bring the car up to 800HP & 800 ft lbs of tourqe - if you can't live with the 630....Let me know.
