I tried this place to wash our SUV. It has been sitting in the driveway was getting pretty covered in pollen and sap. The wash was fast, very fast in fact. I paid for "the works," (for around $10) but it was so fast there is no way it did a thorough job cleaning and applying wax. It is basically a gas station car wash--nothing fancy--that gave my car a once over. All mud and dust was removed, but not all the tough stuff, like sap and bugs. I also didn't notice any wax residue on the windows. To me, that is evidence that there wasn't much of a wax application.
The good news is that it "quick." I doubt much of a line could form because it goes so fast. There wasn't a line at all when I went. I've been caught in some car wash lines for 30 minutes, which makes the speed a nice bonus.
My verdict on this place is that it is a good place to go, but I wouldn't pay for the works. I doubt you get much more.
