GM J platform

By 1990, General Motors began to change its usage of the J platform. To clear room for the 1990 Saturn S-Series, Buick and Oldsmobile ended their use of the J platform (and their presence in the compact segment). Outside of North America, the J platform was phased out in favor of the GM2900 platform (cars based upon the Opel Vectra). The best-selling variants of the J-platform (the Chevrolet Cavalier and its various Pontiac equivalents) would remain in production into the early 2000s, following several redesigns.
