Hello 11 professionals, we have been dreaming of a 997 convertible for some time. Now we have found in an auction a car that we would like very much: 997 4s Cabrio PDK EZ 11/2010 Silver / Leather black 16000 km Bose, SAGA, Sport Chrono, sports seats (looks after GT3 seat on the photos) Dynamic corner light Turbo II wheel Tempostat vehicle is in a hall for storage for 1.5 years, so inspection is due. What can be defective after 1.5 years of service life, what do you have to reckon with? How much can one offer for such a thing? Thank you for your help, greetings, Thilo
