Dirty car? Have 5 minutes? Don't make the mistake of buying a roll of quarters hoping to save time and 5 bucks at a self-serve joint. You'll spend 7 and your shoes will get wet. Full Circle charges 5 (specials for 3) dollars for an exterior wash and it's the best ever. Why would anyone ever wash their own car? Before you enter the circuit a human gives your car a pre-scrub with a soapy brush, after the auto wash/rinse and high-pressure blow dry cycle another human is waiting to do the manual dry. While they are working on your car dig for quarters in the abyss (area between the console and your seat) then you can stop by the self-serve car wash for a vacuum if you need it. I don't know about you but the rest of interior work you get with a full interior/exterior car wash for 15 bucks usually sucks. You can do better yourself in less than 5 minutes with the KFC wet nap you just found under the passenger seat.
