I had three film CLs over the years. While they are a lovely camera, and I think only one of mine ever needed a service, they don't have the feel or rangefinder precision of any of the M cameras. They are/were a great compact 35mm camera with the standard Summicron 40 and Elmar 90 lenses, wonderful for travel. I used to add the original CV Heliar 15 Aspherical to my kit as well, for an ultrawide capability.
I'd sold off all my M-mount bodies and lenses around 2003 to finance other things ... saddest thing to realize was that selling the lenses meant reacquiring them would cost a huge lot more money than I'd sold them for! ... and was back into M-mount around 2011-2012 when I bought the Ricoh GXR with M-mount camera module. I of course wanted another M film body almost immediately.
At that time, I was able to find a nice M4-2 body, marked as "bargain" condition, for $700 or so. What made it bargain condition was the fact that the rangefinder was way out of calibration and the viewfinder full of dust. $100 solved that issue. I still use it today, and I like the simpler viewfinder (35-50-90-135 frame lines) compered to the later bodies. The M4-2, at that time, was much disparaged for some early production issues, all of which have long-since been given appropriate fixes which renders it just as good in use as any other film M, IMO.
I have no idea what relative prices for these bodies are today...
