Seems like the 1M is popular with E9 owners. I have the first one registered in Australia. I've had a run of German cars starting with a 300E Merc, VW Golf GTi, BMW335i and now the 1M. I'm one of the "crashers" having put my 1M into a tyre wall at a local race track. Car was off the road for six months due to a lack of parts in BMW's inventory for such a, at that time, new car.
I've had too many bikes to remember but I'm now a non rider. I just don't have the sense of immortality any more to ride the way I'd like to. Tried a Harley to see if I could have fun going slowly but it just didn't work for me.
I still have a Honda RC30 which is in the final stages of a complete nut and bolt restoration. Everything is here it just needs to be put together properly. If you think parts for E9s can be hard to come by you should try one of these. In my humble opinion it is one of the greatest motorcycles ever made. A real thoroughbred with an extraordinary racing pedigree.
I love to see a classic resurrected and am now the owner of two CS coupes. One is at the bare shell stage for a complete restoration. The usual upgrades with a B35, 3.45 LSD, suspension, brakes, 16' Alpinas, black leather interior and finished in Verona. I have all the original parts including the matching number engine, interior etc which will be kept aside. At the moment it's research, research and more research. My friends see the mad jumble of bits and pieces, give a half shake of the head and say " well, good luck".
Beats watching TV.
