WIXOM, Mich. (AP) - Ford Motor Co. is in the process of tearing down about a quarter of its sprawling former assembly plant in the Detroit suburb of Wixom. Company spokeswoman Becky Sanch said Wednesday the automaker is "in sales negotiations on the property," and the demolition "is agreed upon by everyone involved." The City of Wixom has said the site is being razed "in preparation of a bright new future." The Wixom Assembly Plant closed in 2007 after a half-century of producing the Lincoln Town Car, Ford Thunderbird and GT and the Lincoln Continental. According to figures supplied by Ford at the time of the plant's closing, peak employment was nearly 5,500 in 1973. Wixom Assembly comprised 4.7 million square feet on 320 acres and included 15 miles of assembly line.
