Pricey, but I'm generally pleased with the results. I consider this a once-a-month treat for my car. I see three levels available of which I choose the middle option, which includes some work on the interior. I find the selection of what to get dizzying, with all the possible add-ons.
I forget what the middle level wash is called & I add-on having them clean one or two floor mats. I've been pleased with the results as I figure that once per month is sufficient to have the floor vacuumed & inside windows cleaned. This costs about $30, so the rest of the time when the outside gets dirty, I find cheaper options.
