The Broadside project was the successor to the Lynx, with two versions to be produced. A GT and later a convertible model. Broadside was a sleeker TR7 design to match the extra six inches in wheelbase. The scalloped side panels linked the styling back to the Lynx. Large light clusters on the rear were borrowed from the Rover SD1.

This is the only example of the Broadside convertible, built on a modified and lengthened TR7 platform. Under the bonnet was a two-litre O-series engine designed for the entry level model. Other options included an upgrade to a Rover V8.

Work on the Broadside project stopped in 1980 when the strategic decision was made within the company to cease sports car production.
