Our experiences with Royal Gate have been okay. The service manager is not really that helpful when it came to us telling them about the issues we've had with them. We've been using them on and off for the past two years and there have been times where our oil plug was loose after an oil change. There was another time where they had gotten greasy hand prints on the inside of our car and denied it. The prices are reasonable but the service is pretty inconsistent. We will sometimes get friendly service and sometimes not.
