WOW Just bought an '08 with 1,600 Miles!

[s_c5519]

It's in incredibly brand new condition. Has to be one of the lowest mile 08's in the world, unless Jay Leno has one stashed in his garage...

Have a few questions. I am not mechanically inclined at all. I have a black on black '08 with 15k miles and the new one is black with Sedona interior. I want to keep the newer H2. So I want to transfer the black interior over to the new one (I like the black better). How hard would it be to change these pieces out? I will post a stock pic of the Sedona below so you can see all the Sedona pieces in the front.

Also my 15k one has a very nice expensive custom black velour roof liner. Is that something that is really hard to change over to the new one?

Last question..., the new one does not have NAV and the older one does. Is that a big deal to change over too?
