It's just not a very good car wash. Plenty of spots on my vehicle were still dirty and hadn't been touched by water or soap. The hood of my car is still dirty, even though it was directly hit by the jets. For the price, it's not worth going because hey, you might have to wash your car again to actually get it clean. That shouldn't be necessary.
Also-- no pre-wash or scrub? Seriously? Isn't that the standard at places like this?
