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.

Vehicles at a Barrett-Jackson event in Scottsdale, Ariz., include a 1967 Shelby GT500 Fastback and a 1970 Plymouth 'Cuda with an original 440 Six-Pack.
