Not every dealer marks up the Z06's. Very few around here do any mark up. In fact the dealer I used to sell for sold them just above invoice.went from motor trend test. and used price as tested, because do you think you're going to find very many Z06s that are base models with no options?? i think the GT is pretty much optioned out and there aren't many options. (like the yukon denali) if you want to go with base price the GT:43 and the Z06:66. so there's a 23,000 difference. their price as tested is GT: 43,170 and the Z06:71,485. with the price as tested prices the difference comes out to $28,315.
and then i said that the Z06s are having more tacked on from the dealers that are getting them because you have a car that is limited production and everyone and their brother wants one. supply and demand
the z06 isnt limited production. there will be less gt500's made than there will be z06s.
2 Z06s or 2 C6 vettes? the C6 i can believe, but most chevy dealers dont have that many Z06s. alot of dealers are only going to have maybe 1 vette in inventorywe usually have atleast 3 sitting at the dealership i work at. granted not every dealership is as large of volume as the one i work at, but most of them have about 2.
