and it's not that they are a for sure problem, they could last forever. it is just that like anything, you complicate a simple thing, and it is bound the be the part that goes.

some wealthy are rough and dirty as hell with their cars, but they either pay people to clean/fix it or only have it for a few years. and again, your mileage may vary.
