Formerly known as the Alpine 500. My brother and I did all 5 years of that one in various old air cooled vehicles. Any of these guys look familiar? That orange 911 in the middle of the 1st pic is one. That is my orange 914 all the way to the right in that shot. Hopefully the guys in the 450 SL with the black hood in the 2nd pic were not there, they were a-holes
