[1] Following the retirement of the 300, Dodge's Kew plant was shuttered as production was moved to Dunstable.

A prototype model S306 with a Leyland engine and Weymann bus body was built in 1962 (registered 2498PK), followed by a model S307 with Perkins engine and Marshall bus body in 1964 (registered 3033PE).

These were used as demonstrators by Dodge, but the only orders which resulted were for six S307 models with Strachans coach bodies which were delivered to Rickards of Brentford later in 1964 (registered AYV93B to AYV98B).

These were made in Spain by Chrysler Spanish subsidiary, and included a 38-tonne tractor and four, six and eighth-wheelers rigids.

Sales took off well, and the model was not dropped until 1982, well after Renault Véhicules Industriels took control of Chrysler Europe truck operations.
