Honolulu, HI
Almost everyone I talk to, whether they're one of the people at the front for appointments, or the mechanics, is polite and friendly. In generally I don't expect great customer service when I go to have someone work on my car. The website is easy to use too to make appointments, and even bigger stuff (e.g., getting my tires changed) don't take as long as the competitors. It's a little farther than where I used to go (I live like a block away from a place) but I'll be going here from now on, it definitely leaves you in a better mood when you get to work with nice people. The only negative is that things tend to be more expensive than other places, at least from what I've seen, by a small margin (like $10-$20 on a $150 service)
