I'd say most FF buyers could afford the 458 as well. Personally I like the idea of a fast four-seater, especially if I have other toys to play with. Also I don't think the FF is ugly, 'cept for the silly grinning facia.
Back on point though, a 4 seater GT car that can be used in any weather is surely less useless than a 2 seater hypercar. Less fun too, for sure, but that's not the point of the thread.
Oh, and I'm going to add in the HSV Utes as useless. A ute with a 300kg payload rating? Nuh-uh, foo. My old mini was rated at that...
