Raid the local hardware store add nicely varnished wooden pannels to the already neat vintage adventure. These cars were nicknamed Woodie. I'm just not sure what to go by or of because the car we have, i haven't seen anything like it yet. But you can use a 1937 Ford Deluxe Station Wagon as a reference as it sort of matches up. The vehicle has wooden doors starting all the way from the driver's end to the rear boot lid on the sides.
a woodie station wagon from this era isn't just "slap some wood panels on the side", the body is literally made of the wood. note how even the roof isn't steel, it's canvas stretched over more wood framing. there's no metal in the doors other than the handles, latches, and hinges. And sure, it would be cool, but it's completely different to any of the existing bodies, and would require a lot of innovation in JBeam to make the wood structure behave realistically .
