I am in the process of making the interior of my '87 coupe as perfect as the exterior. With over 128,000 miles on it, it's no garage queen. I drive it to work, in the rain, with my son's car seat in the back.
It was already in great shape, but I am going for perfect. The exterior needed very little, it's original paint nearly perfect. What I did there was easy, so my work begins on the interior:
-Retrofit rear 3 point seat belts using OEM parts from an '88 coupe
-Install Sliverknit Carpet kit from Bob at Appbiz
-Restore front leather seats with Leatherique
-Install new OEM dash vents
-Replace door switches, rubber gaskets, and washers
-Replace most worn interior screws, tapping screws, bolts, brackets
-Replace door seals, threshold plates, and rubber entry panels
-Install Kenwood Excelon AM/FM/CD/iPod stereo and Focal PolyGlass speakers (ipod in the glove box)
-Install new black anodized aluminum interior door handles
-Dye existing door pocket lids
-Rebuild door pockets and lid latches
-Remove, clean, and replace all gauge glass
-Install LED gauge lights
-Replace screw caps/ covers
-Replace front seat belt hinge covers
-Repaint all satin black interior bits as necessary (seat rails, rear seat hinge, etc.).

Also note that the black rubber threshold strip is too short, doesn't reach the forward edge of the door jam as it should.
