If you look at my garage build topic you will see that I've recently updated it with pics of the inside, this includes a friends range rover that I am helping him to sell, this has been professionally detailed with a ceramic coating.
Being black it really shows what can be achieved and it does make it so much easier to keep clean, but I would echo the comment regarding the hardness of the water used when washing, if you can steer clear of too much contact with the the paintwork it would certainly help in the long term.
