I've been to this carwash now 3x's, and it's not even that close to home. I will say that the "free upgrade" does have a lil something to done it. BUT for $5 for a quick decent carwash is not bad, unless your lazy and hate putting in a lil work yourself.
Upon arrival, which btw you can't get into off of University. Entrance is on Priest, I always forget that. Once in you're greeted by an employee. Which I appreciate since I wouldn't know what to do w the Yelp coupon at a machine. I like that they don't solely rely on a machine to assist and take your money, even though they are a cheaper carwash. The wash its self is eh. It doesn't quit get all the dirt off, but for $5 it's good. Since I was a kid I've loved going thru the carwash while in my car. Then once your car is spit out, make your way to the vacuums. Here you will make use of yourself and vacuum your own car, which I like cuz nobody know what spots to hit better than me. However Every time I have gone an employee makes his/her way over to me while I'm vacuuming and asks if they can help. Usually I decline but they do something helpful anyway like windex my windshield or spray off excess water.
As long as the Yelp upgrade is offered, or I'm in the area, or need a cheap quick wash and a vacuum I will return to this spot.
