I think autocross is a lot of fun. Road racing also should be exciting and rewarding if you can do it. In my region, there are no road race courses so, just doing autocross for now. (West Texas Region, [ www.wtrscca.org ]). You can say autocross is cheap too. You dont need to spend a lot money just to race. But if you want to be competitive, you can put a set of race tires and kick some serious butt.
