I wash my car 1 time every week, I stopped going to the car wash bcuz all of the swirl and scratches that did to my car, I would rather now use my energy and wash my car by myslef.
When I fly out of IAH, I always leave my vehicles at The Parking Spot. When you valet, you can get several different kinds of washes. I usually get the ultimate for $99. It is a full interior and exterior detailing. They shampoo the carpets, do the leather, carnuba hand wax the outside, etc. They do a damn good job for the price.
