My car was filthier than a two dollar hooker during Fleet Week.
I was also in need of an oil change. This location is right around the corner from my house, and they did a fantastic job. I pulled in and right away was assisted. I got the oil change and a full service car wash. I love that they didn't try to up-sell me on all kinds of additional services, like air filters. I did decline a decent deal on steam cleaning the interior, but I know they will probably offer me that same deal anytime I go, so I wasn't that worried about passing up the deal of a lifetime.
They changed the oil in about 15 minutes, and then washed the car. They spend a long time going over all the cracks and seams with compressed air to blow all the water out, and then hand wipe the car down. When they were done, I didn't even recognize my car - I had forgotten what color it was under all the Arizona dust. (FYI - it's red).
I have a clean and happy car, and they even found a mailbox key that had been lost for about 7 months!
