Porsche Boxster 986 with high mileage

Good day, I would be interested to know how long 986 2.5 or 2.7 l engines last. Here I have an example, from an offer that interests me:http://suchen.mobile.de/…/showDetails.html?… 169 000 km are a very nice route, but all customer services were done in the PZ and at 160 tkm of inspection. Besides, this is a dealer… …or is that just too much and you have to worry that after another 10 tkm you have an engine damage? PS: I know there is Au tos the drive 300 tkm without any problems and there are those which drop, or scrap already after 20. But a general assessment would be very nice.
