Cant seem to make up my mind between the 2. I love the Porsche, but it is far more expensive. I can get a new SRT10 for the price of used 996TT. I want the car to drag race in, and take to work. Good thing abut viper is its fiberglass, so no door dings. Bad thing is that Viper gets lots of attention. Porsche is all around awesome, less attention, bad for door dings, and much more costly to modify. Both have loads of aftermarket available, Viper being the cheaper to mod. I also want the car to be cool for the long haul, as i intend to keep it for along time.
