Have you considered going the seat rental route for race series like ChampCar, WRL or AER? By far the cheapest way to track and tons of seat time! During a weekend you can easily get 3+ hours behind the wheel. When we have extra stints, we have rented time to friends. Living in Atlanta is amazing with regards to tracks close by, Road Atlanta, AMP, Barber, NCM, Charlotte, VIR, Daytona and Sebring are all within an easy drive.
