I had two perfect like new condition CLEs and they both failed. The shutters kept locking up. One failed a few weeks after I sold it, the other failed a short while later. I had it repaired in the US, but only one tech would touch it and he took forever. None of the regular names would even look at it.
The issue was corrosion in the internals, just basic oxidation from the years. The tech who fixed it went through the camera cleaning everything until it came back to life.
Of note, I store all my gear in dry boxes but I do not know how this gear was stored before I got it.
This camera does have the absolute best 28mm finder out of any RF I have owned (Leicas and Voigtlanders) but because of the experiences I had with mine I cannot recommend them.
