Agree it is easier to clean when ceramic coated, however the more you wash the less the coating lasts and with wash me again tomorrow black (carbon flash) im always going to be washing, wash dry then 2 seconds later need to wash again, but black looks fantastic when clean and shiny.You are absolutely correct - when you trade these in, nobody cares.
On my E-Ray, I have a ceramic coating, but even that is only because it makes it easier to keep clean.
There are some really good synthetic coatings (wax but not wax) that you can apply and they will last a year or in the case of a corvette in Canada 6 to 8 months (something to do when you can’t drive it) and personally I don’t mind waxing (but not wax) my cars thats what I used to do, until I got lazy, I haven’t driven my car yet apart from back from the dealer and I have already put 3 coats of synthetic coatings on it, as I couldn’t drive it anywhere.
Just waiting for the road sweepers to come along then it’s off for a trip out in it.
