    Joe Peters is so kind and helpful. Four stars because it's still making a weird grinding noise in the morning on left turns which was something they were supposed to be repairing. Going back in next Wednesday. So glad to be working with O'Fallon GMC instead of St. Peters. Horrible experiences there
