Make sure you read all the way to the end.

The original letter that I received was signed by Henry Ford. This link doesn't have his signature.
The last time this came up, some bought it and some didn't. I fall into the camp that says it sounds more like the work of a travel writer than of Ford, especially a Ford who didn't drink. It's probably from 1940, but I doubt he wrote it.
And I don't see a single Model T
All the T,s were out on the farms working by the 40,s.

He wasn't that literate. Ghosted or fake. After reading about him refusing to read a loud at that libel trial in, I believe 1920's Chicago, I don't think Ford ever wrote anything besides "You're Fired" and "They'll buy what I sell them".
