The final production day for Oldsmobile was April 29, 2004. The division's last car built was an Alero GLS 4-door sedan, which was signed by all of the Olds assembly line workers. It was on display at the R.E. Olds Transportation Museum located in Lansing, Michigan, until GM's bankruptcy when they retook possession of the car. It is now located at the GM Heritage Center in Sterling Heights, MI.
