My car is almost 17 years old with 170k miles on it, and still doing well in it's main job. I suspect the clutch will eventually go--because that's just a thing that happens, but also because I feel some things while driving that make me think it's not in as good of shape as it used to be--and I've mostly already decided if that happens I'm not going to spend the $ to replace it, I'm just going to get a new vehicle.
On the downside, the compressor, while pretty new, has some weird thing going on where it takes forever to really kick in the cold air, and that's a bad thing for about 4 months out of the year here. It blows cool air right away, it's just not as cold as it's supposed to be, and when the summer really hits, it can't keep up and is not nearly as comfortable as it's supposed to be. Eventually, it gets its act together and starts blowing freezing cold air, but it takes a while. That was okay for a couple of years because I wasn't commuting far. Now, however, with a 50-55 minute drive home every evening, it's going to be brutal, because the car is sitting out in the sun all day and it will take almost all the way home to really kick in, and I'll be home by the time it gets comfortable.
There's some other cosmetic/non-essential things that bug me about it, but just as I've decided I'm not going to spend $ to get a new clutch, I'm also not going to spend $ to fix non-essentials on an older car that may crap out on me any day.
