Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

The seven-passenger touring car had a 50 hp six-cylinder engine, a four-speed gearbox, double internal-expanding rear brakes and a 132-inch wheelbase. Inter-State produced 430 vehicles in 1913, and the factory was later sold to General Motors for production of the Sheridan.
