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.
I have to agree with you in regards to the Model T Ford. Toyota finally surpassed Ford by producing more Camrys in the same amount of time a few years ago. VW came close with the original bug but didnt make it.
And avility to get replacement parts, and affordability for a lot more people. Also the ability to get it in various configurations.
