For me it's alot of reasons. I love the history behind the car, it's AMERICA'S sports car. Also, there is not another car in the world that can do what a Vette does for the money, but it also does it without sacrificing quality high strength, low weight materials like Aluminun, Magnesium, titanium, Carbon Fiber, Balsa Wood, etc. found in the Z06's and ZR1's, which have one of the best power to weight ratios of any production car in the world. You can dog them till your blue in the face and they keep on tickin', I'd like to see some Ferrari's, Lambo's, etc. hold up to what I've put my Vettes through, and not have to worry about a huge repair bill. Corvette also took top honors in the sports car class beating out Porsche as the highest quality, and best sports car. Not bad company! There V8's are velvet smooth and bite with the best of them! I also love the fact that I can still row through the gears myself with a manual and none of this manumatic crap for lazy men, and being able take all the driver's aids off for a totally wicked seat of your pants ride. It doesn't hurt that they look good either. I've got Corvette fever and I LOVE it!!
There are alot more reasons, but I don't think there is enough time in the day for me to get it all in. lol
