I understand what your saying about refinement while keeping cost down. Obviously over the years, the sales price will continue to climb, as the cost to produce goes up. But it seems to me to be climbing faster than it used to. (maybe I'm way off on that point, not sure.

) What was cool about the Corvette was even if you weren't a doctor, rich business owner, etc. you could still buy a used one eventually if you saved your money. I've got to be honest, a new Z06 cost almost as much as I paid for my house when I bought it, and a ZR1...? I make enough money I can afford anything up to maybe a 2007 C6, a first year Z06 C6 is pushing it but possible. While I love the ZR1, I intentionally try not to pay any attention to it because I don't ever see it coming down in price low enough that I could ever afford one. Unless you guys know of one that's been wrecked with 300,000 miles on it.

(I could probably afford that!)
Okay I"m drifting off point sorry. Heh. Long story short, a rolling schedule of improvement I don't think is such a bad idea. As long as the Corvette always has more horse power than the mustang!
