Buy used Porsche Boxster

Hello together, after I have determined that the boxster is already under 20,000 euro to have, the question arises to me what I have to pay attention to everything. how many KM can he have on it, or from which KM it becomes critical. Many boxsters stand for sale e.g. at 100tkm. What do I have to pay attention to so that I have fun with my boxster? How maintenance-intensive are the old boxsters? and which insurance insurances porsche is the cheapest thanks Dennis
