Following the departure of Dizzy Addicott and his DART project, Jem Marsh set about finding a replacement. The car was designed by Malcolm Newell along the same lines as the Mini Jem but clearly not a copy. The Mini Marcos was somewhat simpler in construction and rather untidy at the front with a large flat radiator box angled downwards under the nose.

The new baby made its debut at Castle Combe circuit in September 1965. The track was wet which suited front wheel drive and in the hands of local Mini exponent Geoff Mabbs, the Mini Marcos thrashed the opposition, lapping all but one, a Ginetta, to win by over a minute.
