Spot on sound wise Nordic it was indeed beautiful, I saw it and heard it in 1985 I think it was and I think they actually led the race for a very short period during the first hour as a result of some clever early pit stops 
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)

Ahh the late great Mr Gautlett, I think he had a partner with a Greek sounding name and between them they did pull it all together for a while.
Mr Gauntlet's partner was a Mr Robin Hamilton - don't know his nationality, but I don't think it was Greek!!
