Best cars to cruise in, in real life.

[ricerracer]

Heeeeeeeey, I need some ideas of nice cars to go on a cruise in, I will be going to Italy for a week Holiday in spring and I am planning to rent a expensive car for 2 days to cruise around the mountains. I am thinking of renting an Audi R8 (190 euro a day) but was wondering if any of you guys have real life experience of performance cars (because I do not) and can give me some nice tips on what to pick.
