Wentzville Assembly

Wentzville Assembly is a General Motors automobile factory at 1500 East Route A in Wentzville, Missouri which opened in 1983.[1] The factory originally built full-size Buick, Oldsmobile and Pontiac sedans, and assumed operations of the previous St. Louis Truck Assembly which had been in operation since 1920. Later in 1996, production shifted to building more than 2.5 million of GM's full-size Chevrolet Express and GMC Savana cargo vans,[1] replacing a previous generation of vans built at Lordstown Assembly in Ohio. In 2014, GM replaced the lighter 1500-series vans[2] with the Chevrolet City Express built by Nissan in Mexico,[3] while keeping the commercial-grade models built in Wentzville. That same year the plant began building the Chevrolet Colorado and GMC Canyon,[1] which replaced earlier light trucks built at the former Shreveport Assembly factory in Louisiana.
