From an old Palms press release

"All tier levels offer increasing benefits as you climb the status ladder. Get more information when you visit: http://www.palms.com/club-palms. One rather unique benefit is that the casino has a car wash on its premises! A car wash token can be purchased for $5 or $5 in point value, but All Star level gets 1 token per month and MVP and Hall of Famer levels get two free car wash tokens every month."
