This review is based on interactions with the service and parts departments. Buying the car there (several years ago) wasn't a pleasant experience.
How many service departments charge you less the estimate, have free loaner cars and provide advice that doesn't add to the day's total? How many parts departments would offer to install your wider blades for free? Over the course of a few visits, all of this happened for me at Mercedes-Benz of Chandler.
When almost everyone you meet is friendly & helpful and you receive such good service - you have to say 5 stars!
