The Arizona Vintage Racing Association is an organization whose purpose is to race old racecars. While not prohibiting any type of car, they are mostly Sprint cars, although there are several track roadsters, midgets and a few super modifieds that race with them also. Caged cars and non-caged cars older then 1975 are acceptable. However, installing cages on non-caged cars is recommended. The intent is to give the owners of old racecars the chance to get out on the track and have some fun.
