He's right. Searching is the best answer, although sometimes I find it cumbersome.
General speaking, the HG issues were addressed in the 2000 model year. That is saying 2000 + N* is less susceptible to HG problems than previous years HOWEVER the problem does, at least somewhat, still exist.
From what I've seen and heard here, at 115k, if it hasn't happened yet, keep maintaining the coolant system and most likely you'll be OK. That's a very generalized statement.
Other than that I would say the biggest enemy is failed seat heaters and more so the window regulators.
Not much else sticks out in my mind but I am one of the amateurs that Sub speaks of.
