The Berkeley Foursome was announced in October 1958, this model was wider and longer than its forebears and differed structurally in that the rear swinging arms were lower and external to the body, and the spare wheel was mounted at the rear of the car. The type reference is supposed to be SE492/4 but one has the reference B.100. The chassis numbers are D1/1 to D1/19 but then again one example has D1/100, this particular car could be the prototype since it appears in publicity pictures.
It had a 492 cc transverse two stroke three cylinder, air-cooled engine.
The list price of the Foursome was £700 including Purchase Tax, with an additional £28 for the optional hardtop (equivalent to £12.1 thousand and £485 today).
