People who want to restore a broken-down classic car often don't have the time, the money or both to have it done. That's fine with Dennis Pittsenbarger - automotive authority and veteran race-car driver - and his ace mechanic, `Slick'. In `Highway to Sell', the two partner with car owners to get clunkers back up to speed. Dennis, Slick and their team spend their own money and time reconditioning the cars. However, once a car hits the auction block, an owner has a tough choice: Take a cut of the profit, or buy back the cherished ride at a discount.
