I first found this place when they offered a groupon deal like 8 months back. So having been here 4x now, I can say they generally are pretty good, this fourth time it was 5 stars, last time it was 3 stars. It really depends on who does your detailing.
If you get the ultimate they will clean your exterior, and interior, and even scrub your floor mats. And probably put a very thin coat of wax
I only have them 4 stars because almost every time they don't clean the door jams, or leave a bit of dirt swirls from maybe a dirty rag. These are things im willing to over look cause I don't wanna clean my car in the hot sun, and they generally hustle to finish quickly (expect at least an hour wait).
Also don't leave any valuables in the car. I've never had an issue but I could see it easily being one, and other yelpers have had things stolen.
