By the way, here is one of the Evo owners doing a few laps in a Gallardo with Everyman Racing. As you can see the instructor doesn't ask him to slow down once:
Take their advice though and take some extra cash for some extra laps in other cars. If anybody else is going with you, get them to take their driving licence as well, they may even let the other person pay a bit and have a few laps.
i would drive the 360 just purely for the fun factor and the experience. then once i was done being a mad man, and if i wanted to go really really fast round the track id take the extra to have a go in the R35
