Houston-based Group 1 Automotive, which owns 205 car dealerships in the U.S. and U.K., acquired Estero Bay Chevrolet in Estero from the Winton and Denson families for an undisclosed price. In 2007, Charles Winton and partner Pat Denson were selected by General Motors to open Estero Bay Chevrolet in Southwest Florida. The dealership ranks sixth in Florida and 44th in the nation by Chevrolet new unit sales. Estero Bay Chevrolet is expected to generate $150 million in annual revenues, Group 1 Automotive officials said.
