Is it possible to love a car wash? By adding a touch screen Wiki Wiki somehow has made their most expensive wash $15. Washes are $5, $8, $10 or $15- much more affordable that Auto Bell with free high powered vacuums and no tips necessary. I opted for the $10 wash and was impressed by the vacuum and almost preferred to vacuum my SUV myself - that way I can only blame myself for any leftover dog hair.
