Overall pretty good. OnStar upgrade was done in a timely manner. The only downside. I wanted my summer wipers replaced with my winter wipers which I brought with me with original packaging Did not appreciate my nearly new summer wipers were discarded in the garbage along with packaging without asking me if that was ok to do so. Which it was not! Luckily the tech. was able to retrieve them before the garbage was taken out. Just a heads up to double check next time. Thanks
