The Model T was the most important car ever. Many of these cars listed changed cars. The Model T changed the world. It proved the concept of the assembly line. We have suburbs today largely because of the Model T. Nearly 15,000,000 of them were sold worldwide in 20 years. Before the Model T, almost nobody had a car. After it, seemed like almost everybody did.
The steam car they list was a novelty, no way it was more important than the Model T in that year. That's all I'm saying.
