Out of all the cars I've ever owned the Model S sure seems like the easiest to wash and wax out of all of them. It just doesn't seem to take very long to wash it and then to wax it. Maybe it's the shape, how the design flows. Even the cyclone wheels are easy to clean, rarely have any brake dust to contend with either. I do set the suspension in the 'very high' setting, thanks Tesla Forum for that hack!! Maybe I just love the car so much it just doesn't feel like work to clean it up!
