I agree with the keep it crowd. If you are not having major issues at 90k, I don't see the wheels falling off any time soon. I have several friends that are certified mechanics and they said there is no reason cars these days should have major failure at 100k, 150k or 200k if maintained properly. My brother has 180k on his truck, finally had to rebuild the engine at 175k. My father in law has 230k on his truck and has only had to repair the AC! I believe the 75k thinking (my parents have it) comes from the older cars of the 70's and 80's that just didn't last that long.
I absolutely love new cars and get itchy after having one over two years but I am trying to break myself of that. If your reasoning is the miles, I just don't think you should worry. Car payments suck, I was looking forward to not have one on our truck but that is my sob story.
