It's a good class to start with, that and Spec Miata. Both are momentum cars so teach good driving techniques, good sized fields, many races to choose from in the region, and low upkeep/running costs.

NASA has some good length enduros too, you can dramatically lower costs by selling seats for those. This year they have a 4, 6, and 8 hour race. The 6 hour starts at 4PM...can't wait for that!
