I always liked these films since I happened to see, by accident, 'On any Sunday' It wasn't really an accident, but we had this theater in Northridge, Cal., the Peppertree, that played double features of movies weeks after they made their original release--second run. My older sister and I went to see the Chuck Norris film, "Good Guys Wear Black" and the second feature was "On Any Sunday." Loved both films, but it was the latter that got me interested in motorsports (there were other factors, too). A more recent film was "Dust to Glory" about the Baja 1000 several years back which I recommend to watch, as well. Seeing as you guys are still having late winter, you have some time to catch up...
