Of the one '41 I managed to mostly finish (I had to set it aside, and somehow, large portions of the kit got mangled), the rear suspension was positively vexing for getting it to stay assembled. The windshield divider wasn't exactly fun, either. They should have notched it with a slightly longer back so that it would securely glue into place from inside.
I really love the subject, and have a bunch of these. Even with the warts, they give me something a little different from a Ford or Chevy.
As I've seen observed on this board, with rare exception, cars tend to be "if A does it, B, C,D, et al will never do one," unlike armour or planes, so if Airfix does a Panzer or a P-40 in a certain scale and configuration, Tamiya will copy, then Meng, then Hobby Boss, then Aoshima, and so forth, and then, frequently, a manufacturer will re-do an earlier kit to modern standards with improved fit and detail. For whatever reason, this doesn't happen with cars.
The more I'm looking at this, the more I'm thinking a new '41 Plymouth might be a viable kit, especially if the tooling is set up to do different years. and a few different body styles. It could prove a jump-off for other cars, too.
