What a stupid dealer. I think the biggest appeal of a vehicle like this in that condition is to the people who wish they could buy it new, but missed out.
So to change out the original wheels, lift it, and put larger tires makes no sense. You shouldn't mod something whose biggest value is being in like new condition if you plan on selling it.
Not that I'd ever buy something like this, and I'm not rich enough to pull a whistlindiesel and use it without a care in the world. I guess it's more likely to be a show piece than something you bash around.
