New system just rolled out and includes preregistration with immigration:

Too new to see if there are any hitches or glitches. Probably could be. Site was down last week so I knew something was going on.

This is Banjercito's website for online application for a vehicle permit.

The first panel allows you to select your preferred language.
If you select English, a second panel will present additional options. Select Americano.
After wadding through a bunch of tedium, you will "sign" your name agreeing to follow the rules.
Along the way, you will be required to fill out the INM form Intercasa listed.

If it comes up in Spanish, click on the British flag in the upper left corner. Later the Banjercito application will ask for the file number generated by this INM form.
There is an explanation of what to do with this INM form when you cross the border.
