Spring Hill is the Woodstock for Saturn fans. It was the revolutionary (and expensive) auto plant for GM's Saturn brand. But as Saturn looks for a new voice that does not include plastic body panels and GM looks to shutter a few more North American plants, word is the completely redesigned 2007 Saturn ION will move production to the Lordstown plant where the Chevy Cobalt and Pontiac Pursuit/G4 (Canada/Mexico) are assembled. That leaves Spring Hill with the VUE, which could easily be assembled in Canada with the Equinox and Torrent if it loses the plastic panels. Now the question is if Spring Hill will take in new models from other plants or if the target is on them. The 2007 ION will take a lot of its look from the Opel Astra (shown).
