Non VR-4 Galants were manufactured at the DSM plant. By the way, sweet car (the VR-4). My buddy had a 91 with a 16G etc. SLEEPER!
From DSM.org:
A joint effort by Mitsubishi (three diamonds) and the Chrysler Corporation (penta-star) to build some of the most incredible automobiles in the world. The vehicles were produced with the names Eagle Talon, Mitsubishi Eclipse, and Plymouth Laser. DSM cars are assembled in Normal, Illinois. The '94-and-up Mitsubishi Galant is also assembled at the DSM plant in IL; previous Galant's were assembled in Japan. The Eclipse and Galant (since '89) share the same platform.
