A bit more progress yesterday. One the rear wheels would not cooperate with the Firestone logo. There was a spare decal and I killed them both on the last wheel. Not going to sweat it... once the diorama is figured out, it'll be hidden.
I do like the grey of the interior. The instrument panel is almost completely hidden below the dash. Unfortunate that the details are mostly obscured but it does make the missing vent a non issue.
The door cutouts seem odd to me. I don't see them that way in any photos I can find. Regardless, I'll either paint the inside of the car body black or I'll attach a bit of blacked out sheet styrene to the door itself.
You can see that there is only a bit of the engine/transmission that will be visible.
