If you look on racingjunk.com you can find a couple retired Touring cars. $100k will buy you a reatired mazda 6 and $20k will get you a protege. Both of which were pretty sweet cars. It would be badass to buy either for a weekend racer. As sweet as it would be to run a series, I would be all giddy about going to a Road Atlanta track day or something a few times a year.
