CUMMING — Lou Sobh Honda held a grand opening event Aug. 13 at the dealership on Buford Road. While the location has been open to the public since the end of 2013, the gathering gave company leaders an opportunity to celebrate the success of the facility with the community and Honda executives. “Usually with a car dealership, you want to wait a little bit longer for a grand opening,” explained Mike Sobh, vice president of the company and son of Lou Sobh.
