This is an international event, in which several classic car trophys are gathered in one major weekend event.
They join the historic F1 (in several age groups, ranging from 1950's till 70's and 80's), GT cars like Mustangs, Cobras, Jags, MG, Porsches, and many others. Again all separated in techological and age groups. There's the Datsun 1200 trophy, Motorbikes... You have it all basically. Even an awesome reconstitution of the Slalom that used to happen in the 1980's after the great Rally of Portugal.
I was there also, but just on the outside, because i wouldn't have tim Euro to use the paddock tickets. Work's a bitch. Here's a couple of pics i've taken. EDIT: I was trying to post the pics, but then i realized the limit is 200Kb... Didn't it used to be bigger?!
I'll resize them later... There's a Carrera GTL Abarth (i think it is one) in one of them
