Four stars for The Carwasher if for nothing else, convenience. The $4.99 special to run your car through without having to wait on any waxing, hand drying, etc. is a great bargain and comes in handy when you're in need of a quick rinse.
This is nothing close to a high-end auto spa, and you'll notice that the second you walk into the waiting room. It's in need of a serious makeover in there, but this place gets the job done and I've never driven away unsatisfied.
