I just realized that there were LP 400 S (S1) made with periscopa roof. How many were made ? Must be hard to find now. This is one example: http://www.lamborghiniregistry.com/Countach/CountachLP400S/1121030.html More question: Does the LP 400 S (S1) has the same dashboard and speedo as the LP 400? I have many books on the countach including the one by Marchet & Coltrin, unfortunately none has detailed info about S1, mostly S2.
