I scanned some of the cars for sale websites this weekend and noted that several Carrera 2.7s that were for sale are not now listed and presumably sold. This includes two that have been discussed in this thread:
1976 C2.7 # 911 660 9084 which had an asking price of 140000 Euros &
1975 C2.7 'Anniversary' model # 911 560 0225 which was 130000 euros.
I wonder if indeed they have been sold and if so did they make anything like the asking prices which seamed quite adventurous.
I also came upon this French forum which discusses the Siver Anniversary one including a letter from the restorer and a copy of a COA from Porsche.
