if you are going to buy the Viper I would strongly suggest you and the misses take a high performance driving class. I would hate to see the car and possibly the mother of 2 damaged from driving a vehicle that is not the most user friendly
That's exactly my point. The Viper is a really hard car to handle from many perspectives.
Really, if you want something fun to drive, thats fairly quick (not as fast or powerful as the viper) and something you'd feel comfortable and safe letting your wife drive. Go with the Vette.
And just to clear things up, the viper IS Fiberglass, just like the Vette. Either way, they both have pro's and Con's.
But from what I know, and if it were my family I would choose Vette. If only from a safety perspective.
