1928 "Al Capone" GM Cadillac V8 Town Sedan
Price: $621,500
The famed gangster's personal car was painted green with black fenders for a reason other than a homage to the almighty dollar -- it was also the color of the 85 Town Sedans used by the police. That clever move was classic Al Capone, who also ordered the car outfitted with bulletproof steel plate and heavy glass. The mobster's wheels included a rear window hatch for firing Tommy guns at any pursuing vehicles.
