The miles you cite are low and of course, you HAVE to have a PPI, performed by a Porsche Dealer.
We have had guys on here who have NOT done this and they have regretted it terribly.
Also, run a car fax and make sure your dealer does a paint meter check on the car for bodywork.
If you search the threads for Pre-purchase advice you will not be sorry.
The answer to your question lies in prep BEFORE buying.
Best of luck to you.
