More specifically, its American market cars that are crap. My favorite American car you can't actually buy in America: I had a 2008 Vauxhall Zafira 1.9 CDTi SRi when I lived in England. 6-speed manual, turbo diesel, sport button, and I could fit all my friends in it (seating for 7!). It got over 40mpg, and was fun, quick, nimble, and felt well built. But even though its a GM car, since the engine hasn't passed emissions testing in the US, it is illegal to own here.
I own a Volvo and my girlfriend has a Saab, so I understand where you're coming from. European built cars are of a far superior build quality. I laughed out loud after a hailstorm this year here in Kansas. All the American, Japanese, and Korean cars around mine in the parking lot were damaged or totaled by hail. The Volvo was unscathed.
Not all American cars were bad though. While I have a recent Volvo XC70, I also drive an 83 Chevy Suburban 6.2 Diesel, mostly as a daily driver. Its in nearly perfect shape, with 247k miles, power windows, power locks, comfy seating, and it gets 23mpg. Not bad for a 6300 lb truck that can haul a 5000 lb trailer. Its one of the most reliable vehicles I've ever had.
