I used to be a Porsche dealer and I am the co-owner of this site.
IMHO I would NOT own a used Boxster out of warranty. That is my personal choice, one that cannot be justifled or denied by DATA, which is simply not available.
As to the warranty availability, you have two basic ways to go. To be a Porsche extended warranty, you will have to buy a CPO car from a Porsche dealer.
Your other choice is an aftermarket warranty. The rules on these all vary, so check them out BEFORE you buy any Boxster.
And always get a PPI on any Boxster you are considering BEFORE you buy it.
Good luck. Do more searches on this site for some great buying tips BEFORE you buy.
