First of all, I've absolutely no relationship with this company.  However, Rent-a-Racecar has recently acquired a Brunton Stalker V6 that you can hire to takr round the track.  They're based at the Virginia International Raceway Resort Motorsports Resort, which in addition to having a great circuit, also has an outdoor pool.  Prices from $200 - $1000 depending on duration and car.
