I did a rally day at a place near Silverstone back in '02, and it was immense. Driving a proper Group N Impreza around on a loose surface was just so much fun, and there were no limits put on the car or anything. Something like that, or the Caterham experience would be so much more rewarding than 3-4 laps of anything in a rev & gear limited supercar. Alternatively, a regular track day in your own car would be a good option.
For some people, they might be perfectly happy just to drive a 458 at 3/10ths, but I'd personally find driving something slower at 8/10ths to be much more rewarding. Caterhams, Elises, rally Imprezas, all far more fun.
