Royal Chevrolet on RT 22 in Bridgewater is great. Used them for my C6 and they can do an engine rebuild, which I’m not sure how many dealers can do. I just bought my C7 at Richard Lucus on RT1 in Avenel NJ, but don’t have any experience with service with them. I'm debating whether to do my own fist oil change or have the dealer do it and see if they mess it up.
