Here's a pretty good reason if you care about your own country's economy. There's a lot bigger picture than where a foreign corporation builds a couple of their models. Look at where the engineering, design and safety testing is done. Look at the number of Americans each company employs. Look at the wages American car companies pay their US assembly line workers vs what foreign automakers pay their US assembly line workers. A lot of people may not care and that's their business, but fortunately a lot of people do. The argument that "my foreign car is built in America" gets old fast there is a lot bigger picture. These numbers are from 2012 and the gap is even wider now:

Detroit Three vs. Japanese Three: 181,000 to 67,000
Car dealerships and suppliers often sell cars or furnish parts for multiple automakers. Take them out of the equation, and Detroit automakers have the clear lead in direct employment — at assembly, drivetrain, stamping, casting and tooling plants, research and design facilities, U.S. headquarters, testing grounds and the like. GM spokesman Fred Ligouri says GM employs 77,000 Americans. Chrysler's U.S. employment totals 39,200. Ford declined to provide numbers, but the American Automotive Policy Council, a group that represents the Detroit Three, says the Dearborn, Mich., automaker employs about 65,000.

Combined, that's more than 2.5 times the number of employees that Toyota, Nissan and Honda – the three largest Japanese automakers in the U.S. — employ. Toyota spokeswoman Carly Schaffner says Toyota employs more than 30,000 Americans, up from 29,089 in 2011. Honda has "just north of 26,000" at its U.S. operations, says spokesman Ed Miller. Nissan's U.S. operations employ 10,380 across six states. Hyundai-Kia employs 7,800, according to two spokesmen for the Korean automaker.

Just to be clear, everything you state in your first paragraph is simply your opinion. I feel the exact opposite regarding everything you said and feel that American vehicles are superior in every way. That is my honest opinion.

On top of that, I care about what is better for the US economy and what is better for American workers.

American vehicles are a whole lot different today than they were in the 80's. I think America's overall economy plays an important role in one's individual finances.

All of the ones that I've owned do. That's honestly not just a slapstick response. I've had nothing but great luck with American vehicles, including quite a few with very high mileage over the last 30 years.
