It does look like a ton of fun since most mere mortals will never have the opportunity to drive such incredible cars. Yea, it's expensive... but i'd do it if I hadn't already driven most of those cars.



Ferrari 599 or Ferrari F430 Scuderia: Drove a Novitec-Rosso F430
Maserati Gran Turismo Drove a friends.... hated Maseratis ever since
Audi R8 Drove 2 of them. Probably the most fun you'll have out of bunch.
Lamborghini Gallardo Superleggera: Had some track time in a regular Gallardo.... amazing car. Found it funny that it's climate control was the same as my 2007 Audi A4. I found it more "fun" to drive than its big brother, the Murciallago
Ford GT: Haven't had the opportunity
Spare:
Mercedes-Benz SLR McLaren: I think it wouldn't be that fun unless they let you crush the posted speed limit



Anyways.... I say go for it. Try skydiving too. I'll be doing my third jump in a couple weeks!
