Unfortunately my 2001 got rear ended last week. It had 112,000 on it and I traded it rather than repairing it. I used the car and insurance payoff to purchase another vehicle. Anyway, with the mileage you are talking about I would check: rack and pinion, front suspension, exhaust leaks, struts and shocks, sway bar links, oil leaks, brakes, O2 sensors, etc. all of which I had replaced while my daughter drove it, up to last week when I was using it.I'm going to take $2,500 and shoot a $2,100 or $2,200 offer first and go from there. But to answer my question, what are some things I may need to look forward to with it having 170K miles?
