The topic frequently appears about the lack of suitable automobiles for the first decade following WWII. It appears that convertibles and 2 door hardtops seem to dominate the limited selection for this era. Since my free-lanced B&O and NYC railroad is set in the summer of 1955, I must be very selective of the vehicles that are on the roads and in the parking lots. Affordability is paramount for a lot of us and even though I do have a few Brooklin models of some otherwise unavailable autos (think Kaiser-Frazer, Dodge Wayfarer, etc.), Brooklins' price point is rather high considering that there are some very good alternatives.
I just recently acquired a very good and (relatively) inexpensive replica of a 1954 Pontiac Chieftain from "American Excellence" diecast modelcars. At $24.95 +s&h, the value was excellent given the quality of the model. "White Box" was the name of this model line.
There are a surprising number of affordable and well detailed examples of ordinary, commonplace two and four door sedans representing the 1945 thru 1955 era.
