after weeks in sonora and southern arizona during monsoon season, the dust on the outside of my car was so thick, you couldn't even tell the exterior was black. the inside was worse -- kids had often ridden with me and there were stains on the seats and the doors. i'd been in a similar situation a few months before and had brought my car to another carwash in phoenix that is manipulative about air filters and really not that thorough in any interior detailing. los olivos is on the other extreme, in terms of service and results. they gave my little yaris the best cleaning its ever had! shiny black on the outside and sparkling clean and stainless on the inside. worth every bit of the $85.
