The PA Cresta was announced on 2 October 1957. It mimicked the American fashion for tail-fins, wrap-around windows and white-wall tyres, taking its cues from the 1957 model Buick Special announced twelve months before the Cresta, though understated compared to the Cadillacs and Buicks of the time. All factory-built PAs were four-door saloons: the estate cars were converted by Friary of Basingstoke, Hampshire and are rare today.

It was well equipped with leather and nylon upholstery for its bench front and rear seats and woven pile carpet. A heater was fitted as standard. The radio was an option on the home market. Other options included fog lamps, reversing light, locking filler cap and external mirrors. In order to keep the front floor clear to seat six people the handbrake lever was mounted under the dashboard and the gearchange lever was column mounted. The car could be ordered painted in either single or two tone colours.

During the 1970s many PA Crestas were modified and customised. The model was very popular with fifties revivalists; many were driven by teddy boys and were very much seen as part of the rock 'n' roll image. A 1960 PA Cresta features in the 1981 video for "Ghost Town" by The Specials, in which the band are wearing '50s-style clothing.The Specials Ghost Town Car can now be seen in the Coventry Music Museum.
