I've been taking my car for oil changes and smog checks for the last couple of years. Many times I've been tempted to go to other places but, always go back because I like that they vaccuum the interior of my car. The only thing that bugs me is that sometimes the vacuum job gets a little shoddy, that is if they do it at all. I've learned how to get around this though. First, take the car mats out of your car and vacuum them on your own from the front and back. They tend to do a better job if they don't have to move anything. Then cross your figures that you have a worker that actually gives a poo about the back seat and your set!
