Joe have you thought about building a shelter for it that isn't ugly on the eyes? Ultimately I know a second garage is in store and you'd keep it in there.
As long as you wax it you should be ok keeping it outside I mean it is a boat and look how many mansions on the water are out in all the elements and still look nice....all about the upkeep. What about a trailer with a fold away tongue?
I would prefer anything I own to be inside but if it isn't possible I would take the necessary measures to ensure it will hold its shine for years.
A good wax and boat cover should do that, and if you can a structure over top would work even better.
