I love this place! I go here frequently especially in the winter to get rid of all the salt and gunk that accumulates on my car. For just $8, you get a great exterior wash that comes out looking impeccable - very, very shiny. For just a few bucks more, you can get your interior cleaned and get an undercarriage flush, which can be handy towards the end of winter. I like to watch as my car goes through as well (I'm easily amused).
The staff is always very friendly and courteous and never try to push anything extra that you don't want.
I would gladly wait in the long line that there generally is here in the winter to get my car cleaned.
