I was just at the Mercedes dealer looking at a 2017 B250e and it says the Engine and Transmission are made in the Netherlands and the car has 0% US/Canadian parts content. That does not seem correct, even the tires on the car said "Made in USA". My 2015 B-Class says Engine and Transmission are made in USA and it has 15% US/Canadian parts content. Is Tesla still the battery and motor supplier?
