I still love my GTS after three years. Usually I am bored before a new car is even paid for, but the Viper is just such a unique and outrageous car, it keeps my interest up. But I want something else, too. Like a Ford GT, or GR1. Kinda like having a mistress, and cheating on your Viper? I want to collect fine cars if I can, and don't see any conflict about owning other great cars.
There are a lot of cars that are performing in Viper territory now, the new ZO6 will be close, that bi-turbo Benz, (SL55?) and a few others.
But I'll keep the GTS because I absolutely love the way it looks and handles. If it starts fallng behind in power, there's always Roe or Paxton. Its a timeless design worthy of updating. I can't think of any other car I have owned that I can say that about.
