Too bad about the rust, but this is a super complete and likely matching numbers 1956 Porsche 356 Coupe that I photographed in a barn the other day. The owner bought the car in the late 60′ when he was stationed in Europe for the US Military. He drove the car in Germany in the winter which he thinks was the start of the rust issues on the car but what great memories he must have.
I really like these cars and believe that they will be valuable enough to bring money that justifies getting this car back on the road. The details like the instruments and clock, the door frames without the 1/4 vents and original Becker radio. The owner wants to sell the car and get into a complete 356 so if you know someone who wants such a project, keep me in mind.
It isn’t quite the oldest Porsche in the USA, but if these get you going, check out the contest being run by Porsche in conjunction with their 60th anniversary in America. https://porsche.promo.eprize.com/60years/?loc=interstitialskip
