Two completely separate threads...
Ford Fiesta is mfg in multiple global locations. NA sales are coming from the Mexican plant.
In general, US auto mfgs have significantly improved quality, matching the best in class, and sometimes blowing away the competition. Kia, HORRIBLE quality ratings. But, good cheap transportation.
Now, on to Detroit... I drove through a previously thriving business area, and my wife pulled her firearm out of her purse and put it in the door pocket. A war zone would look in better shape. There are still some areas that look great, and the downtown area is making tremendous strives to improve. the new mayor is a successful business leader, and he was actually a write in candidate that won. They have some unbelievable debts, but bankruptcy will help to clean that up. Lot of people are beginning to step up. Will they succeed, IDK, but I'm seeing more progress in a short period of time then I've seen in decades of decline.
