wow sounds like this has turned it to quite the intersting topic, but i figured i would through my 02. cents in anyway. Both cars are totally in a league of there own, the new Z06 is just nuts, i mean looks at the times the thing posted at the nurberg in in germany, i believe it had one of the best times for the track, beating porshe's and etc hands down, and yes it maybe 10-15 grand more in the price deptartment, but i think the car is a more all around car than the GT500, and just think this is a NA car, granted its 7 liters but hey look at what ligenfelter did with it after they got there hands on it.

so to say that the GT500 with just a few bolt ons will be able to destroy the Z06 and Viper, i mean the ligenfelter and the henessey viper are on the rarer side but i just do not see anybody comming close to what these companies have done with the vette and viper even in there "tuned down" packages, And yes i also belive that ford was worried to much about making money on this car rather than, trying to devleop and test new things, i mean develop and lighter motor, work with the
suspension, etc etc etc. and there is what i think is wrong with automakers today, i mean take some time to throughly develop things, dont just shove it out there trying to make the quick dollar, and improve as years go on, i mean this should have been one of those 1-2 year "special editions" like the anniversary ta's and etc, but people will find alot of flaws in it and i dont think after a few years of production it will have the same luster. so in short to say i would own one yes i would but to compare to a Z06 or viper or of the like i think is a little over the top.
