Price: $1.2 million The King of Rock 'n' Roll drove this posh convertible during the 1966 musical comedy Spinout, in which Presley played a combination musician/race-car driver. (His character raced sports cars, but used the Duesenberg for everyday transportation.) One of just two 1929 Duesenberg Model J Phaetons ever produced with a dual cowl and a short wheelbase, the car sold at auction in 2011 for $1.2 million. Duesenbergs were the Rolls-Royces of their day, starting at what would be the equivalent of around $270,000 today. The brand was so exclusive that some experts believe the expression "a real doozy" originally referred to Duesenbergs. The Duesenberg used in Spinout features a 265-horsepower engine and an exterior custom built by one of the 1920s' best "coachwork" firms. RM spent months before the auction restoring the vehicle -- a good move, since Presley apparently dented the car's underside during filming. Actually, the musician is said to have apologized to the owner at the time, gotten the car fixed and offered to trade a new Cadillac and some cash for the Duesenberg.
