6. William McKinley, Stanley Steamer
He may not have owned this car, but McKinley holds the distinction of being the first president to ever ride in a car. It was a steam-powered coach called the Stanley Steamer. Yes, that Stanley Steamer. The company built cars until the 1920s, and Taft included a Stanley Steamer in the White House’s first fleet of cars. It would have looked similar to the 1905 Stanley Steamer pictured above.
