The Wicky car failed to start the race the following year, but they had better luck in 1973 as they were joined by the Swiss driver Philippe Carron.

For 1974 Wicky ran a De Tomaso Pantera for Cohen-Olivar and Carron, but the duo retired in the fourth hour of the race.

In 1977 Cohen-Olivar joined the French ROC (Racing Organisation Course) entry, driving a Chevron B36 alongside Alain Flotard and Michel Dubois.

For 1979 24 Hours of Le Mans, Cohen-Olivar joined up with a new French entry under the Lambretta banner, sharing a Lola T298 with Pierre Yver and Michel Elkoubi.

He remained with Lemerle in 1982, who with support from Italian firm Sivama Motor was able to run a new car, a Lancia Beta Monte Carlo.
