First time visit to Cobblestone in Scottsdale, though I have been to the one off Signal Butte in Mesa (near highway 60).\nIn short, and after spending close to $38 for the Ultimate Plus and leather treatment of my seats, it is easy for me to conclude that I would rather take my BMW 535i to a Full Circle Car Wash or a Francis and Son's car wash for one simple reason:\n1. Much less cost for a more effective wash, dry and detailing.  I spend less then $20 for better work at the other two (2) locations.
