Probably for something as simple as Transportation Authority rear-view mirror specification mandates. Although a brilliant idea for a Prototype Show-car, it was likely deemed unsuitable for a Production Road-car.
Yes, it was on the LP400 Periscopo but was non-functional. Those cars had a convential rear view mirror as Joe mentioned.
For clarification, all production Countach LP400 were built with just the notch in the roof with skylight which was retained as a design feature, there was no 'Periscope' mirror, just a standard rear-view mirror.
Just came across these ones that I didn't know before. Maybe a repost from some other thread but at least it fits quite well in here. Image Unavailable, Please Login Image Unavailable, Please Login
Amazed after all these years to come across images that are new to me. I wonder how many unseen / unpublished are out there? Image Unavailable, Please Login
A couple of slightly differing shots, of similar pictures, but again never seen before by me. Image Unavailable, Please Login Image Unavailable, Please Login
Just for good measure. Not new shots, but missing from this thread. Image Unavailable, Please Login Image Unavailable, Please Login
I found this image as a very small thumbnail many years ago. Thrilled after years of searching to have finally found this image in hi res. Image Unavailable, Please Login
Another new to me shot, similar to one in this thread but a new angle . (Picture 1 is in the thread already, picture 2 is the new angle)
