ABC was an American high wheeler automobile built by Albert Bledsoe Cole in St. Louis, Missouri, USA, from 1905 to 1910.
Known as the Autobuggy from 1906 to 1908, it was sold as "the cheapest high-grade car in America", and was available with two-cylinder and four-cylinder engines, friction drive, and pneumatic or solid tires. The drive system used a cone and two bevel wheels, one for forward and the other for reverse. This allowed it to reach its top speed in either direction. A larger engine was fitted in 1908, and the wheelbase grew from to . Its high ground clearance made it popular in rural areas.
Later models were more conventional with two- or four-cylinder engines, but the market for high wheelers was disappearing and the company folded in 1910.
