This all really depends on how you maintain and how you drive it while its in pain. Here I think the longest life we've seen for a Boxster 986 (the'r all dead now btw) is little over 150k miles. Gives you an idea of what this little car is able to endure with practically zero maintenance
That's right, here we buy car > beat/burn them > and buy new again! Repeating that same process all over again. We believe that maintenance is a waste of money lolllll (I know, don't ask!)
