Now that's just not right. These things are for driving - they aren't museum pieces. I don't know if I'd spend much time on the street with it, but if I could afford one, you can bet I'd be plunking down some cash at the local track pretty regularly. Hell, give me a nice big piece of land and I'll build my own road course for the thing.
McLaren had one that was clocked at 240 mph, for crying out loud. But I'd have to verify that for myself, to make sure I got my money's worth. No limey carmaker is gonna stiff me ;)
