Like I caught some crap when I bought a BMW X5 several years ago and some yokel said, "Too good for a Murkin' made SUV?" which is probably built in Mexico or Canada whereas the BMW was built in South Carolina.
Only 35% of the value was as it wasn't bult there, but largely just assembled. You can look back several years ago to see if that percentage was higher or lower. GMs recently moved a lot of their truck production to Mexico, but it's still has more domestic content on a percentage basis than what BMW's offering. There might be 4 or 5 models tops between the big 3 and all their brands that have a lower percentage than your BMW.
