Agree. The last time I saw an 850 driving around (outside of a Fiat event) was over 15 years ago. And X1/9's are rare sights now (at least in this part of the USA).
While the number of operating 850's is relatively tiny, there must be many stuffed away. More will be put back onto the road now that they are becoming more "interesting". They do have a lot of charm.
My x1/9 project is still patiently waiting for the 850 to be finished. A couple of pics here:
