Interesting mystery, I had to dig into it. Turns out it is a check digit use to ensure the VIN is valid. Basically a single character hash of the VIN, which should be 0-9 or X. If any number of letter on a VIN was entered incorrectly the 9th digit would help detected that.
You can test it yourself with this VIN check digit calculator:

The ‘wasted’ dummy digit #9 just seems weird though… Logic would say it’s a code for something, lol. Not a field for a random character generator (if it’s a dummy it could have just been the same value in all VINs. It sits in between the ‘type’ info and the “date” info… damn, what could it be?
Any idea how many of the 4WS models were made? Or 5MT versions?
