As far as let somebody do it car washes go this is the only one around that is hand wash and not brushes. Problem is that after time and time again telling them that you don't want the shiny, goopy interior dressing they still do it. Then you have to go home and spend another hour scrubbing that off. This is especially frustrating after you tell them multiple times not to put it on and to just use a damp cloth to wipe it down. $50 for the good was then another hour at home getting the crap off. Keeps me from returning often.
