I had a new salesman who did much better than I would normally expect. The sales manager was great as well as finance. The only issue was in getting Onstar working. The partners who do that wasted nearly two hours having the salesman repeat over and over again processes that did not work. Finally, a knowledgeable person fixed it. I suggest the dealership intercede with whomever the salesman dealt with to be sure that process is not inflicted on another customer. My salesman was always polite and helpful.
