Congrats on the new project. Sounds like it will be a great bird once you get it finished, and I too am kind of partial to a polished exterior! One thing to think about on that, is painting the parts of the plane silver that are constantly dirty and seldom seen like the belly, underside of the wings and tail surfaces, and tops of the wings. Mine are all painted silver, and when the airplane is clean, you can hardly tell they are painted.
On the interior, Im sure it could be pricey, but I saw an MAF 206 at the local MAF Repair facility with a pretty slick interior. It had what looked like selkirk (or similar) panels and a maple floor with a Brownline Track system installed front to back and tiedowns all over. I would love to have that system in any "utility" interior. Pretty cool.
The seats are made by a company called JAARS. They are not available to the public, as I understand, and are made for crash survivalbility, not weight savings.
