31. Auburn "Boattail" Speedster
Not only were the boattail Auburns some of the most beautiful cars to have ever been made, but they were some of the fastest, as well. At a time when Cadillac was competing directly with Rolls-Royce and its most powerful engine managed 90 horses, the Auburn put out 115 and topped 100mph. In fact, Auburn's test drivers took each speedster out onto the highways around Auburn, IN and made sure of it. For a while police tried to give them tickets but were incapable of catching them and eventually gave up.
