The Nimrods ran earlier than that, in fact they ceased production in 1983, and last raced at La Sarthe with a fiery exit on Mulsanne in '84 (one car hitting the other which was already on fire).
In '85, the EMKA Astons were running, and it was one of these (No 66 - Dow Corning) that led the race for a stunning 9 minutes due to a clever re-fuelling strategy. It eventually finished 11th that year, and was driven by Steve O'Rourke, Nick Faure & Tiff Needell, the same line up as raced the first EMKA car in '83 (they didn't race in '84)

Delboy, you are of course absolutely correct, thanks for putting me straight on this.
