Ah, I used a third party source which was missing the Model 3 Long Range specifically, which is 75%. Maybe it was not listed because it is limited to that one trim. Then there's the Model Y and the Model 3 Performance at 70%. All other American brand vehicles are < 70% and most are 20-40%

The top vehicle from the big 3 is the Ford F150 at a whopping 45% US/Canada.

My point is that if you buy any car in the US, you are buying a vehicle with significant foreign manufactured content.
