I haven't owned many cars. My last car was a 2007 Subaru Impreza wagon, 4 speed auto purchased new. Alternator went at 38k, just 2k miles after warranty expired. Spent way too much getting that fixed
Other than that, car was good.
My family on the other hand - '99 Chevy Suburban LT. List of things that have been replaced - all of them, lol (due to age/use, not premature failure - most of them, anyway). Basically the only thing that wasn't touched was the V-8 engine itself (solid as a rock) and the stereo. Car is still running @ 180k miles just fine ... starting to rust out though.
The car did have a serious design flaw with the A/C lines - they run under the car and corrode. Had them replaced twice and finally gave up when the A/C failed the third time, as it will just happen again.
