“Where the HELL could I drive either car the way they deserve to be driven?”
There are numerous road circuits in the US where you could drive one of these cars as it was meant to be driven during an open-lapping day. If I could afford an R8 or a Gallardo (though I’d much rather have a 458 Italia), I could probably come up with enough scratch to take it to a track now and then.
I don’t know of anyone racing a Gallardo, but the R8 is classified for competition in FIA GT3, Pirelli World Challenge and USCC.
I guess we always find the money for things we REALLY want to do.
