Thanks guys for the opinions.
Believe me Paul, I've thought about everything you've said already. As far as mileage goes, the Z06 actually gets 18/29, which isn't far off from us actually.
It is a bigger car, that does suck. Parts prices are a little expensive, but bolt ons for the vette yield much better power. As far as my car goes, it's on its 3rd tranny and 2nd differential, so you can see how I feel about it. I've dumped 6,000 in non-warrantied repairs for the sky in less than 2 years, that's not even counting the performance parts I've bought for the car. At least with this Z06, the LS6 block is just fine up to 500-600 whp and the tranny/diff can take it as well.
Insurance is of course the big one. I'm speaking with them today about a quote. And as far as what I could get for my car is another big one, which I'm trying to swing by my dealership to ask them that question.
Z06's, although large, do very well in autocrossing so i can still have fun tossing the car around.
I'm still just in the speculation stage, I was just kinda thinking out loud really....and no it's not the meds
I've been pondering this for over a month now.
