I went in for a full detail with a Groupon. The work was done on time and looked very good. The one thing keeping this from being a five star review is that they really went way overboard on the vinyl protectant, and I had to wipe it off areas like the steering wheel and door handles. Otherwise the car looked very good.
Also they have work areas set up with computers, and a large lounge type of area with nice chairs. I waited for the car to be done and just got some work done with my laptop in reasonable comfort.
