If I were you I would find a local Porsche club and enlist their help. Any Porsche you buy from a used car dealer could have major issues just like buying from a private seller. Cars belonging to club members generally have a better chance of having had all their scheduled maintenance.

Parts will cost more for a Porsche than they will for a Chevy so keep in mind the fact that you should budget money each year for parts.

You might also consider getting your hands on a buyers guide book like these for the 911
