For those who love to wash their own cars, it just doesn't get much better than this. The place looks kind of aged but it seems to be very well maintained, I've had no problems, and the little cleaning supplies vending machine worked fine too (reasonably priced, too, no insane markup).
I am only taking off one star because while I love a clean car and will spend money for it, nothing floored me so much that I had to keep coming back. For the price, I can get unlimited automated wash plus fast and detailed detailing by careful human hands (not my own) by being a member/subscriber of a certain facility in N. Scottsdale on Via Linda. I realize automated machines run the risk of marking up the car with swirls and the like, but a wash plus unlimited detailing for less than the cost of going to Spirit Car Wash once a week was something I couldn't pass up.
