I think I have some news that you will enjoy!
In the Soviet Union, they copied many US car models. Not surprisingly, there are many 1:43 scale cars that are made in the ex-Soviet Bloc. Nice models can be picked up on da'bay for ~$8-20. The only issue is that most come from the Ukraine and Russia, so don't expect fast shipping. I would suggest buying in bulk.
I have a few on my layout and they look perfect in my 1920s-1960s setting
