I just moved to Phoenix a few months ago. I wasn't used to how dirty my (dark colored) car would get in such a short period of time. I tried another place and it was good, but way to pricey to do on a regular basis. After having my car parked at the airport for a week I decided to try Hog Wash since it was close to work. I was a little thrown off by the self vacuuming, but got over it. I was extremely impressed with how good the wash was for the price. Vacuuming it out myself wasn't even that bad. Would definitely consider the monthly pass.
