Where do you live? Why do you want/need AWD?

Do you want a coupe? Convertible? Manual? Tiptronic? There are LOTS of options on these cars, maybe consider ones you deem "required" or "nice to have" or "don't care". Read up on some of the maintenance / cost of ownership concerns as well.

I'd look on Pelican, Rennlist, Craigslist, Autotrader. Also consider joing PCA for more advice.

buying from a dealer that is not a Porsche dealer can make having a PPI more difficult. Buying from an independent has plusses and minuses. Be sure to get a carfax account to check available public records.
