The exhibit showcases more than 750 antique, classic and special-interest vehicles spanning nearly 200 years of automotive history. Of these, more than 200 are on display-and for sale-at any one time in a gallery-like setting on the fifth floor of the Imperial Palace's parking structure. The constantly rotating collection features vehicles once owned by famous and infamous people (James Cagney, Elvis Presley, Al Capone, Benito Mussolini).
