Glenfrome Engineering from Bristol was mainly transforming Range Rovers into 6-wheelers and convertibles. However, in 1975 this small company launched the original Delta coupe prototype. It used a mid-mounted Triumph Dolomite Sprint engine. This model remained a one-off. In 1981 the famous designer Dennis Adams created Facet model for the Glenfrome company. It was a very angular all-terrain sports coupe based on Range Rover. Approx. 20 examples were made and most of them were sold to middle-east countries. A replacement model named Profile was introduced in 1985.
