Just to throw out an alternative that's not on your list, I saw that you can rent a Mercedes AMG SL55. If you haven't driven one, this is a whiplash inducing vehicle which I think you'd actually find easier to drive fast in a straight line than a Viper or Ferrari, particularly without an extended period to get used to the nuances of the car. I'll certainly concede that the Viper draws more attention in some circles, but after driving one for a while, some of the annoyances of the car will wear on you. You've done the Ferrari, so I think you'd get less bang for your buck on the second go-round. The AMG SL55 is faster than the Porsche cab, looks better (sorry folks) and IMHO conveys more of an impression that "you've arrived" than a Viper or 996.
