Henry Brown Buick GMC

Several very disappointing service experiences. The latest with a mystery diesel fuel leak requiring several trips to service, and a mess in my driveway... still with no resolution. Three minutes at another dealership's service department and the problem was diagnosed and repaired. To add insult to injury, the vehicle is always returned to me dirty with grease marks left behind from the technicians that worked on it. Isn't Henry Brown part of a larger company named General Motors that is trying to regain market share? You guys still have a lot to learn about Customer Service.
