Christ that's an ugly NSX, poor car didn't deserve that Why won't people just leave the bloody things alone and appreciate them for the stunningly beautiful car they are instead of bolting plastic tat to them!
I think I'd be tempted to run a Caterham for a while, just to say you've done it. Buy now when the weather is (normally) crap, run it for a while and sell at the end of next summer, you may even turn a profit and almost certainly won't lose out. Benefit of running a shed is that you can get away with stuff like this. I think I'd almost certainly be looking at C6 'Vettes too and the odd decent Mustang as well if you like Yank V8 noises.
