Well, here (finally... ) are the finished pictures.
Paint is... none! Gasp!
Yeah, that's right, none. The black plastic body panels were so perfectly polished and shiny right out of the box, I knew right away that there was no way I could ever come up with a paint finish to match that. Painting just isn't my thing... actually painting a body is my least favorite part of building a model. So I left well enough alone.
I did a custom interior, because these were real high-end cars in real life... custom coachwork, anything goes, really. Like contemporary RRs, the only limit a customer had was the size of his bankbook... so I upholstered my interior with a pretty wild animal print-type "leather" and added custom "leather"/wood/chrome insert door panels. The seats are aftermarket resin items... much more realistic than the kit-supplied units:
I used an aftermarket steering wheel, horn ring and wheel hub. I also used clear Lexan to cut new windshield glass; the kit supplied glass was too thick and way out of scale. The new "glass" is mounted in in-scale "rubber" gaskets made of styrene U-channel (you can see that "gasket" right at the middle pillar, by the rearview mirror. Dash is covered in real wood, glove box handles are made of silver paper clips:
On the dash, I simulated the "mother of pearl" gauge insert panel with a piece of paper from the scrapbooking aisle at Hobby Lobby. The paper has a pretty realistic "mother of pearl" pattern printed onto it. The MB logo crest on the wheel hub is part of the aftermarket steering wheel package:
Actually, I used a lot of aftermarket parts on this one... interior and exterior door handles, wipers, hood mesh inserts, grille mesh, headlights, etc...
The cloth convertible top really works. I didn't want to mess with the tiny PE buckles so I left it open, but it really does work (honest!):
