Whats the oldest car available

ie any 1930s 40s or 50s cars

 

must be the Gasoline Alley 2016

 

There is a 3rd party 1937 GP mod. It's only 0.1 version tho.

 

I have been working on bunch of cars from 50s, but realizing that something underneath in rF2 is broken with solid axle physics demotivated me a lot, so can't continue. Also I have 1937 Merc W125 car, which I would love to bring, but it makes no sense to do if it won't be possible to simulate properly.

 

I have some old vintage le mans car pack installed, think its OSD. I think some of them are from 1954.
Cant remember where I downloaded them from but think its from steam.
