William McKinley – Price Undetermined, Stanley Steamer
William McKinley was the first President to experience a car ride. The car in question was a steam-powered coach called the Stanley Steamer. He was so impressed by the vehicle that he ordered one to be among the very first car fleet ordered for the White House. It was probably done without a loan. You can see something similar in the 1905 models of the Stanley Steamer photos here. The cars actually arrived while William Howard Taft was President and the stables were transformed into the garage. McKinley never got to see his cars because he was shot in 1901 by Leon Czolgosz and died eight days after.
