Everyone knew the Butch Cassidy star was a car enthusiast, but this? In 1988, Paul Newman bought a Volvo 740 Turbo—only to swap out its modest four-cylinder engine for a 3.8L turbocharged V6 from a Buick Regal GNX. The result? A power jump from 154 to 300 horsepower. But Newman didn’t stop there—he replaced the stock transmission with a five-speed Borg-Warner manual and added an “Aero” style body kit. This one-of-a-kind Volvo, built to his exact taste, recently sold for $80,000—not an unreasonable price when you consider the legend behind it.
