I always go here for my car washes because it is close to my house an convenient. Their express detail package is legit. I pay $49.99 for a regular clean as well as one detail service, normally I pick an extra deep clean of my seats and cup holders called "Super Interior Clean." If you don't do that the basic inside and outside packages vary from $15 to $35 - very fair! I've never been blown away by their service, and there have been times that I have waited hours and hour for my car back from the "express" detail. I think four was the longest and I was not pleased. However, it is still close to my house and they normally do a decent job for a decent price. You get what you pay for.
If I were giving advice, I would say don't wait there for your car. Drop if off and go do errands with a friend/spouse/coworker or whoever. Then have them drop you off when Fabulous Freddy calls you. If it gets close to closing time CALL THEM because they will leave your car there.
Always tip!
