Casting 73C, the Mercury Commuter, is a station wagon, commonly found in green with a pale interior. The model may be most notable for the two dogs in the back cargo area, peering out of the open rear window. Initially offered with Autosteer, the model was later converted to Superfast wheels.
The Mercury sedan police car is also related, sharing its original base with the Mercury Commuter. Josiah Carberry Collection.
This shared base bears the numbers for both the Mercury Commuter and the Mercury sedan police car, and a generic "Mercury" title. This example is on a Commuter with early (thin) Superfast wheels. Josiah Carberry Collection.
