80K miles on a 2007 model is extremely high, but i always hear these stories of people who drive a lot and their vehicles hold up beyond expectation. i presume most of those miles were highway miles, which also makes a contribution.
back when i was drive 80 miles a day for work, my honda civic had no issues at all. then, when i switched jobs and relocated and my commute is now only a short 10mins of driving...everything started to fall apart. the transmission crapped out on me, and the engine is definitely not running like it used to.
i really think with vehicles, the more you use it (long trips / highway miles), the longer it will last you
