Isn racing a BMW expensive?
Racing is very, very expensive and time consuming, irrespective of car marque. Older BMWs have many junk yard parts and performance modifications available, and tend to be very reliable. In general, smaller, lighter cars in less prepared classes tend to be less expensive to race as they go through less brakes and less tires. Additionally, smaller engines cost much less to rebuild. There are probably cheaper cars to race — but when all things are factored in, they may not be as cheap as they look initially. If I was going to build another race car, I would seriously consider a Mazda Miata. Mazda has a fantastic program supporting amateur and semi-professional racing. BMW could take a lesson from Mazda — Mazda’s program fosters a strong, pro-Mazda enthusiast community.
