It sounds like a pretty good deal to me, but you may want to have another place inspect the car(PPI) just to be sure. It will cost you a couple hundred but it would be a good idea if you have any doubts and it will give you peace of mind. There are many that say never buy a used Porsche unless it is inspected by an idependent source. Even Porsche dealerships hide some things they might not want potential buyers to know about.
