I get my car washed here a few times a week with my membership. I don't know what all the hubbub is about getting tricked into getting a membership, as they require you to fill out the make/model/color/etc of your vehicle and give you a receipt that states all the terms. I would never fill out all of this information for a single wash, so I think this complaint is pretty unfounded. It's just a decent no-touch wash that has plenty of convenient locations, which helps someone busy like me to keep my car presentable. Sometimes I bump my head on the metal vacuum canister when I throw something in the trash, which is a drag, but I'm apparently terrible at learning basic lessons.
Serious tip: If your spouse gets a plan, join up with theirs to get a great deal. I didn't know my wife had one when I joined, but they made switching the plans easy when I went back.
