I have an Italian 5 speed car. I believe there were about 850 Pagodas built with 5 speeds. Total production that includes 113, 112, 111, 108 and maybe 109 was around 1,400 so they're very rare regardless of what car they were used on.
I once saw a 300SE Cab with a 5 speed. One of only 3 made and it's part of the MB collection. I wonder how much THAT one's worth?!
