That's because most of the guys who are into Fords/Chevy's have been around for a while.

A lot of the import kids are just that, kids. Like little girls, unable to appriciate cars.

There is a difference,however. I've never seen any bias out on the autocross course. All the rivalry is in good fun and sportsmanship. There is no hate, there are no put-downs. Between all makes and models, everyone respects everyone.
