Development concluded after nearly a decade in late 1997, with pilot production models being produced into early 1998 bearing R396 DTU registration plates.

Aside from the radiator grille, badges and wheels, the Seraph was externally identical to the contemporary Bentley Arnage, sharing both its platform and body shell.

Standard electronics included digital engine management, adaptive ride control and anti-lock brakes.

The Seraph was known for its relatively limited acceleration and comfortable handling, in comparison to the Arnage, which had a twin turbocharged V8 of its own design and firmer suspension.

An extended wheelbase 5-passenger version of the Silver Seraph called the Park Ward debuted at the 2000 Geneva Motor Show.

Introduced for the 2001 model year, it had 250 mm (9.8 in) added to the size of the doors (mostly the rear), resulting in more leg room for passengers.
