The Commuter 1 is a four door sedan. Like the rest of the Vehicles in Crackdown 2, except for Agency Vehicles, the Commuter 1 is rusty and in poor condition. It has rounded edges than its "twin", the Commuter 2. It is based on the Chevrolet Chavalier.
In Crackdown, the Commuter 1 is slightly better at performing, and is much less rusty. They are also less common, though regularly appearing on the Highways.
