Hello dear Porsche friends I’m currently driving an SL 500 From Bj 2008 Mopf Become a 997C 4S convertible for me in the near future, I’ve already found an interesting ad. It’s about this car http://suchen.mobile.de/…/details.html?… Unfortunately, I have no experience with Porsche, neither with the value maintenance, since now the new model comes out. My question to you: How can the value preservation be estimated? Is the above offer about expensive? What is an essential It ́ ́must have ́ ́ ́ What a ass must have? Would you rather advise me not to buy this car because it doesn ́t have one or the other extra? And a question that is very important to me: Is a 911C 4s mopf in all concerns faster than a SL 500 mopf? I thank you in advance for your answers and hope you can help me further or make me a little smarter bzl the 997 4s Mfg Gino-hh
