I want to get in my Civetta Bolide, take it to a road on the edge of a cliff and race against CPU's, just to see how long I can last.
Take a Grand Marshal, drive it around the island(?) while crashing into things. I'd really like to cruise on some winding mountain roads with the Civetta Bolide.
The air isn't the natural habitat of most cars... But yeah, a Dukes-Of-Hazard style crash would be awesome.
take a supercar thats not made to go off road, let alone rock climbing, and go rock climbing with it, which will then destory the suspension XD
