My friend and I tag team car washes here frequently. It is self-service and only a dollar for 3 minutes. You can do a whole car in 6 minutes...sparkling in 9 minutes. We always work it with one person washing while the other one wipes things down with a rag/towel. They actually have different fluids for the settings (I think there is about 8 different settings).
Wash Around the Clock also has vacuums that do shampooing as well, although some are better than others. There is a drive through car wash, but I have never used it.
If you don't mind getting a little dirty and putting some elbow grease into washing your own car, for only a few bucks this place is great!! Not to mention a good half hour work out, depending on how much work you put into it ;)
