I clean the Zed every week with fail, more often than not twice a week, last week was 3 times.     A normal clean takes 1 & half hours, and a full wax/groom etc, is about  4-5 hours.  Then you have a show groom, which will take about 2 weekends.  Grooming engine bay with soft tiny paint brushes, interior grooming, the works really.   
  
Well I think I quality for Zed Obsessive Complusive Cleaning Disorder, I may have written the book.
