That's actually a real neat looking vehicle featuring some really cool innovations. Not being an automobile enthusiast I don't have much knowledge of their history or specifics. I'd certainly like to grab one if I could find one for a fair price.
If I were a purist I'd have to veto it and any of the vehicles I have been able to acquire so far. The story is supposed to start in 1922 and the oldest period car I have is a 1925 Panhard

.
Luckily I see them as old cars and don't notice that sort of thing. I further identify the Mercedes as a fast old car. Nice finds at the show! I have a small group of cars collected that are passable for the setting but I need to find some trucks.
I weathered the tires after reading about the state of Canadian roadways in the 1920's. No wonder people liked travel by train.
