Just my two cents: I doubt that the identification as a Somua is correct. In 1955, Latil, Renault heavy trucks and Somua were merged to form Saviem-LRS (= Latil-Renault-Somua), soon to become just Saviem. The Latil and Somua brands were discarded with the merger. Why should Renault revive the Somua name for a Jeep-related vehicle in 1986, when they owned about 50 % of American Motors, thus Jeep itself?
