Unfortunately Windsor joins the ranks with the others closed during the most recent downsizing. Oklahoma City was the first to close in Feb 2006, just 90 days after GM announced plans in November 2005 to shut several facilities. OKC was only 26 years old and had produced 5.5 million quality vehicles since it opened in 1979. After GM spent $700+ million in 2002 to build midsize SUV's in OKC and rebuilt a new paint shop destroyed during a May 2003 tornado, the assembly plant was one of GM's most updated, yet older factories escaped the cut. GM had other products available for assignment, but the $200 million offer from the state of Oklahoma wasn't enough to convince GM to stay in OKC. GM instead chose to try and sell the GM plant in OKC for a paultry $55 million to the county for use by the Air Force base nearby. Good luck, sometimes these decisions don't make much cents!
