I recently tried buying American. I wanted to support the US auto industry and I liked the Mustang a lot so I bought a 2010 back in February. What a piece of junk! To make matters worse, Ford acted like they were doing me a favor fixing all the issues with it. When I tried to get them to buy it back, they refused. Long story short, I ended up selling it back to the dealer I bought it from at a loss. When I sold it, it was in their shop on it's 5th visit for repairs in 4 months of ownership; a total of 21 days. I know I could have held out a while longer and took it to court under the lemon law, but I just wanted to get on with my life.
This ordeal changed my whole outlook on this issue. As far as I'm concerned, if the American auto industry or any American industry can't hold it's own and build a superior product, it does not deserve to exist.
As for me, I'm sticking with Hyundai from now on. In fact, my wife and I just bought a new Kia Soul for her so now we're a 100% Hyundai/Kia family.
