This special one-off based on a standard Princess 2200 was extensively re-styled by Ogle Design to enable Triplex to demonstrate its most modern glass technology.

The windscreen is Triplex Ten-Twenty laminated glass and has a Triplex Hyviz coating, incorporating demisting, de-icing and an aerial - all cutting edge in 1978. The wing mirrors are made with similar de-icing glass.

The one-piece rear glass hatch is remarkable for the sharp curvature achieved and the glass sunroof is made from very thin, flexible glass. At only 2.3mm thick, it enables the sunroof to be opened by simply bending the glass.

The 10-20's design was completed by Ogle's unique front and rear end styling, including an integral bumper and rear light display.
