Depending how far you are willing to drive, Boyle Buick/GMC in Bel Air has been family owned forever and has among the best reputations in the area. Do a quick google search and you'll see they have a 5 star rating on Google which I have never seen before.
They have always been more than helpful in all of my family's dealings with them.
