Overall condition, lack of rust, maintenance history and asking price - these are all more important than whether it has 125k or 250k miles on it. As others have said, buy the best example of one that you can find within your price range, with a savings for maintenance/repairs. I looked around for about four months until I found a non-nav LX with 169k mi, most maintenance records and no rust. Then it was just a matter of baselining it after purchase (timing belt, fluids, etc) and it's been a great daily driver for the past six months since I got it. Zero regrets on this truck.
