I wanted an easy way to always have an updated list of the Car "Makes" in the United States. It doesn't change that often, but if it does, hopefully this list will auto-update as the data is pulled and parsed from Wikipedia.
Here's a link to the Google Sheet if you want to edit anything: https://docs.google.com/spreadsheets/d/1lBk9CjGCkbMNqzbehkdpxa7VyEDRZjh-5Nx2QcpbvOE/edit#gid=108045673

And here's a quick and easy options list for a select input of car brands/makes in the United States (as of Jan 2020) that you can easily copy and paste:
