A-Train I have had 4 911 turbos 87,91,96,01, 2 M3's 99,01, 1 01 ZO6 and 3 Vipers 98,99,01. Turbos as follows 87 Turbo(tweeked) larger turbo, larger intercooler, Borla exhaust, boost control, this car was wild and unpredictable lots of fun. 01 Turbo (tweeked) 12.79 quarter mile at 117 mph fast and more refined than my 87 Turbo never lost a race, only competition were motorcycles. 96 Twin Turbo no turbo lag smooth handle great not as much fun as the 91 Turbo or the 87 Turbo. 01 Twin Turbo Boring I was very disapointed with this car in styling and performance did not have the immediate torque I was looking for, not a good street car for racing. 01 ZO6 fast almost as fast as a Viper but just another Corvette, no one knew the difference. New 01 M3 fast, fun, beautiful in styling one of the most balanced all around performance cars. 98,99 and 01 Vipers by far the most exciting car on the planet, tweek it and have more fun I have not had more fun in my 01 yellow Viper than I can remember, looks, finger pointing, pictures, people asking for rides there isn't a better conversation piece than a Viper. As far as everyday use I would rather drive the M3 or ZO6 more comfort.
