I've been dreaming too long and it's getting to the point I will have to pull the trigger. I want a fast car that I can take to the track and romp around in on nice days; not a daily driver. I'm looking for a driver's car. TC has to be able to be turned completely off and I'll probably kill the ABS, too. Any thoughts on what the best car would be for driving experience and speed (both acceleration & top speed) between these vehicles kept stock. I really prefer corners and have no interest in drag racing. I'm looking at an '04 Z06, an '05 base Vette, an '06 GTO, or a first Gen Viper. Anyone with experience in any of these vehicles, please let me know your thoughts on them. I have never driven any of them. Obviously, some will require more time saving money for them than others. I would really like a 0-60 time less than 4.5, but has to be less than 5 seconds. Preferred top speed >180. Any other vehicles that may fit the bill will be considered. Has to be able to be purchased for less than $30K.
