These two camps are not mutually exclusive. Obviously I'm driven by OCD, but I clean the Morgan after every trip. Washing is rarely needed though, just fly removal, and a wipe over of the wires and exhausts with a rag and WD40 - sometimes polish. I also do the tyre sidewalls inside and out with a spray on shiner. I've had trouble over the years with sidewalls cracking after a short period, so the shiny finish helps to keep them 'moist'.
It's not a chore with carpet tiles on the garage floor.....
I polish gratuitously whether it needs it or not.
