Yeah, from what I hear, that's pretty normal with American cars (particularly GM and Ford): the drivetrains are usually very reliable, but the interiors are terrible and fall apart quickly, and the rest of the car looks like crap before long too. But the thing never quits running so it keeps getting used even though it looks awful.

I honestly have no idea why anyone buys American cars, unless they don't know this. Probably they're a little cheaper than imports.
