The Focus is made by Ford but very small. I rode in one a few years back and it was not as "sturdy" feeling as my Civic. There were noticable rattles and creeks. I was not impressed.
The Fusion is nice but it is a Mazda. I have to admit that I do like my friends '08 Fusion SE. It is loaded with leather and all that stuff. He paid around $28k for it. Too expensive for me however.
I drive a '97 Civic. Bought and paid for many years ago and still kicking strong.
Sooner or later I will need to replace it though. When I do, I will be going for max value over brand. I could care less where it was made, if it was made sh!tty. While I would value a US made car over a foreign made car, it is not enough for me to take a "risk" if I felt it was not the same quality.
The US cars that I have liked lately are some of the GM cars like the Malibu and the G6. I am just afraid that the nice design does not equate to a better quality vehicle. I should drive one before I make up my mind though.
I owned a '94 Grand Am at one point and remember driving it off the lot (my first new car) and thinking what a nice car. Then a month later it started falling apart. The alt went within 30 days. The radio was next, then the A/C, and finally the sunroof. I sold that thing within 6 months of owning it. I lost $5k. Never went back to a US car since.
