They may think their classic cars are priceless, but owners get a true sense of what their rides are worth in this longtime Velocity series. Sports Car Market magazine Publisher Keith Martin provides the critical, expert eyes auto enthusiasts need to properly determine value. He visits car auctions across the U.S. to test drive some of the world's rarest automobiles for sale, from powerful muscle cars to stylish European sports autos. After an in-depth inspection and a deep dive into each car's history, Martin determines an accurate value before it races across the auction block. Comic/actor Josh Nasar ("Sons of Anarchy") -- a collector car junkie -- joins Martin on many episodes.

Keith Martin and Josh Nasar attend a Barrett-Jackson auction event in Scottsdale, Ariz., where they drive a low-mileage Ferrari 512 TR and a survivor 1967 Corvette.

Josh takes a spin in a 2005 Ford GT, a sports car inspired by the 1960s GT40 that achieved success at the 24 Hours of Le Mans.

A rare Lamborghini Miura SV, one of only five single-sump SVs sold new to the United States, hits the auction block in Arizona.

Keith cruises in a restored Alfa Romeo Giulietta Spider Veloce; Josh drives a 1997 Porsche Turbo S, which was the last 911 Turbo manufactured with an air-cooled engine.
