We wouldn't be too concerned about the mileage if the price is right - Hondas handle high miles well and it's probably better that it's been used for regular long journeys than lots of short journeys around town. It sounds like it might have been used as a fleet car for its first four years, covering high miles with a company car user, before being sold to a private owner. I wouldn't be too worried about this as long as there's evidence of regular servicing. We'd generally choose a newer, high mileage model as long as it's been well maintained.
