In the movie Ronin, when a getaway driver wants "something that can shove," he requests an Audi S8. With 360 horsepower and a lightweight aluminum chassis, the old S8 has a bit more power than a 2009 A8 while clocking a few hundred pounds less on the scale. So yes, it's got some shove. And all-wheel-drive, a sumptuous interior and a 75 percent discount off the original price.
Our Find: 2001 S8 in Ohio. Pearl with gray leather, 68,000 miles. Nav system, xenon headlights, Bose sound system. Resale value is helped by the fact that this is definitely not the car used in Ronin. $17,999
