Can't speak for the full-service side, but the self-serve is the most worthless car wash I've ever been to. One of the bays had the "Soap" option subtly taped over it with masking tape to indicate that it wasn't dispensing soap. That seems to be a mission critical function at a car wash. Instead of indicating that the bay was out of service, or even putting a clear sign that soap option wasn't working, they left it so that someone could easily get duped. Fortunately, I was paying attention. Also the towel dispenser failed to deposit the $1 towel I purchased and when I did get a towel, the wringers were so old and dry-rotten, I was able to easily wring more water out of the towel with my bare hands than with the wringer. So, this is a dump, but I will say the Weiss Guys at McDowell/67th Ave, while dumpy-looking, everything functions well. Two stars because I was able to find a bay that was fully functional.
