About a year and a half ago I bought my car, an 87 Carrera Coupe with 21,000 from a guy in Pennsylvania who specializes in used Porsches. He seems to deal with cars in excellent condition and his prices are fair for what your getting.
I found him to be exceptionally honest. In my case I lost out on the first car that I looked at because I took a day to think about it because I had another appointment set up for the next day.
He called me as soon as he got the car that I eventually bought from him.
His website is
