Vegas Baby!

If you want to feel power get the Viper. If you want the exotic/once in a lifetime feeling get the Ferrari. If you want to save money or fit more than 2 people (uncomfortably), get the Porsche. I would recommend the Porsche to most people but not a Boxster owner... it won't be anything special to you. I would personally get the Ferrari.

996 Cab is for Britney Federline. Just kidding, but I really think coupes that have been chopped are not kosher. Ditto for the M3 Cab.
Which came first the 355 spyder or the Berlinetta?

Ferraris are the ultimate head turners. Its physically impossible to not watch it drive past if you are female.

Vipers maybe on the track (they did well at LeMans a few years back), but
not in Vegas.

Ferrari. Looks great in red.

All data is scientifically proven. Statistics were included standard T-test, standard deviation can occur especially with Ferrari, in case if driver is handsome and wearing proper things, with heart open and smiling.

T-tests (Student's; I don't believe there is a "standard" t-test.) are not valid when comparing more than two groups. You'd have to do an analysis of variance (ANOVA) followed by a relavent post hoc test, assuming you get a main effect of vehicle. I prefer the Scheffe' as it is very stringent.

Of course, the point is moot, get the ferrari and you'd get looks from chicks (assuming they know something about cars or have functiong ears) and from guys (wish it were me in that car).

A Ferrari and a pretty female with long legs is ideal for the strip. If you live in the midwest, America's own bread and butter is the way to go. Back Country cruising to explore the boutiques that Nantucket has to offer would be most appreciative in a Porsche 996. Hope that helps.

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.
