The cars that are now selling for over $100k on a regular basis at the BJ auction? they would be "resto-mods" of classic muscle cars. these cars are old muscle cars with modern engines, drive trains, suspensions and even interiors. even the owners of BJ that were interviewed about the state of the collector car market stated that the price leaders in the past - being original, numbers-matching muscle cars - are now being replaced by the resto-mod vehicles as the collector car market continues to change and evolve to new tastes with younger buyers.
