General Motors' brand-new Lansing Grand River (LGR) vehicle assembly plant was officially opened this week. It's GM's first all-new U.S. assembly plant since construction began on the Saturn plant in Spring Hill, Tennesse in 1986. Construction began in late 1999 with production of the new 2003 Cadillac CTS starting in the fourth quarter of 2001. The plant began shipping cars to Cadillac dealers on January 7.
