Hi Hunter1300,
A bit of trivia from Portugal
There were between until 2010 a big championship for Classic cars until 1980 and until 1300c.c.
The best race was Boavista Circuit in Porto in 2009. 44 cars attended the meeting including Minis MK2, the populars Datsun 1200, Mg Midget, Alfa Romeo 1300 GTA and Alfa Romeo Sprint, Ford Escort 1300 between others.
Now the championship is a bit down with grids between 10 and 14 cars..
Best regards
Diogo Ferrao
