Covisint had an attractive offer to occupy six floors in downtown Detroit's Renaissance Center, but the automotive Internet exchange spends a little more money to keep its world headquarters in suburban Southfield, MI.

The company decided against the Ren Cen because it did not want to be too closely allied with General Motors Corp., which is moving its world headquarters there.

GM helped form Covisint two years ago, along with Ford Motor Co., DaimlerChrysler AG, Nissan Motor Co. Ltd., Renault SA and, later, PSA Peugeot Citroën. In early ‘03, the company and its 300 employees will move to Two Towne Square, a 9-story building under construction.
