As has already been mentioned, American companies go to other countries chasing cheaper labor rates. Many cars list domestic content or where major components were manufactured. When my wife was trying to talk me into trading in my Mountaineer on a mini-van I noted the Mercury Villager had a Japanese engine, while the Mazda MPV had a Ford engine.
On the other hand, foreign companies build vehicles here to get around tariffs and import quotas!
This has been allowed to go on for decades because of fear of trade barrier retaliation, if not in motor vehicles, in another product area.
The profits from the domestically built foreign company vehicles don't stay here, and I don't know if they are counted in the balance of trade numbers.
My " American" Mercury Mountaineer was assembled in Canada, and had the Canadian Firestone Wilderness tires. I had to wait until round two for the tire recall.
