The situation was made easier in autumn 1981 by the conclusion of purchase contracts for three chassis, which were delivered to three customer teams at the beginning of 1982.

During the race, both cars were repeatedly forced to make unscheduled stops in the pits due to a number of technical shortcomings.

[5][6] While there were almost no racing successes in the IMSA GTP series - it was only in July 1982 that Skeeter McKitterick was able to place an M382 in the top three with third place overall in the 100-mile race at Sears Point - the works car counted in the sports car World Championship for the fastest and most successful vehicles in the field.

After finishing second overall in the 1000 km race at the Nürburgring (driving Henri Pescarolo and Rolf Stommelen ), fifth in the 6 Hours of Silverstone (Pescarolo and Gordon Spice ) and fifth overall in the 1000 km race of Spa Francorchamps ( François Migaultand Spice) Rondeau seemed certain of the overall victory in the one-make cup of the sports car world championship.

A counter-protest by Jean Rondeau was unsuccessful, after which the enraged Frenchman announced his factory withdrawal from the World Endurance Championship, both as team boss and driver.

The best placement of an M382 in the following years was the seventh place (chassis 005) by Pierre Yver and Bernard de Dryver at the 1000 km race of Monza in 1984.
