"Mac's" car is a Checker A-11, manufactured in Kalamazoo, Michigan. Manufactured almost exclusively for Checker's own nation-wide taxi company, it was favored for its large rear doors, large trunk, and great durability. In addition to taxis, Checkers were also available in limited numbers to consumers. Due to its small scale of operation, Checker could not offer the kind of discounts seen with the major manufactures and ceased manufacturing its own vehicles in 1981.
