The Mini Marcos was produced in limited numbers between 1965 and 1970 by Marcos, 1974 to 1981 by D & H Fibreglass Techniques Limited and again between 1991 and 1996 by Marcos. It was based on the DART design by Dizzy Addicott who finally sold the project to Jeremy Delmar-Morgan. Jeremy marketed the Mini DART as the Mini Jem. Jem Marsh of Marcos cars separately developed the project into the Mk I Mini Marcos and despite the similarity of the name, had nothing to do with the Mini Jem. In Sweden the Mini Marcos was sold by Elmhorn-Troberg Racing Service.
Following the closure of the Marcos company, the Mini Marcos moulds were acquired by Rory McMath of Marcos Heritage Spares who has re-launched the car as the Heritage Mk. VI and GT, the latter being a racing version.
It was the only British car to finish Le Mans in 1966 and set four British land speed class records.These are the flying mile, half mile, half kilometre and kilometre for cars up to 1600 cc.
