They also bought a pair of Brabham BT44B Formula One cars, and entered the 1976 World Championship, running Loris Kessel and Emilio de Villota for the Spanish Grand Prix, where neither qualified.

However, both Kessel and another pay-driver, Patrick Nève, qualified for the Belgian Grand Prix, with Jac Nellemann, Damien Magee, Lella Lombardi and Bob Evans all making appearances in the cars.

For 1977, Boy Hayje drove a RAM-entered March with little success, and a second "rent-a-car" did no better later in the year when driven by Andy Sutcliffe, Mikko Kozarowitzky or Michael Bleekemolen.

Kevin Cogan and Geoff Lees would guest in another car in the last two rounds, but their best finish was Keegan's 9th place at the United States Grand Prix.

1981 saw RAM manage and run the returning March Grand Prix team, with Derek Daly and Eliseo Salazar driving.

Salazar returned to drive the main entry, while a second car for Jean-Louis Schlesser was fielded at the French Grand Prix as a one-off.

Kelly's new design was disappointing, and the cars were frequent back-markers, and Palmer's 8th place in the opening Brazilian Grand Prix was their best result of the year (and of all time).
