Squadra Piloti (it means "team of drivers" in Italian) members can make arrangements like swapping their exotics for a specified time, or simply renting their bahnburner to a member whose daily driver is, well, sub-exotic.
If having an F1 pilot as a member is important to you, Squadra Piloti's uber-driver Scott Speed is up against Club Sportiva's Mario Andretti. Tough act to follow, Scott.
Check out the Squadra Piloti website for more info. If you try it out, let us know how it goes! Maybe Scott will rent you his Toro Rosso ride...
