thats a bonus, and helps widen the search, seen some for sale at 110-130k and that put me off a little.
That's not to say I haven't had to spend any money caring for it though! There are a few threads on high mileage, but I'd say watch out for worn bushes (front banana arm and differential in particular), which can of course be replaced but it's not an easy job on your own. Check for any advisories on the MOT sheets, etc... Ask what fuel it has been run on (should be premium fuel for correct combustion). But overall, other than general advice, I don't think there are many issues specific to the 350Z to be concerned about.
