I looked at getting an R6 or R6.2 a few years ago and found quite a few people reporting problems with mirrors, meter circuits and lagging shutter releases. Some get great service from them and some have used them professionally although in the case of high profile users I would guess if there's a problem they just unbox another and carry on. Sadly my experiences with Leica have always been a bit of a lottery and although my list of problems is short it is more than I've had with any other manufacturer.
To be fair to Leica we must always remember that in these cases the cameras are old and have probably not been used regularly or stored poorly affecting both mechanical and electrical integrity.
All my R4's except one had sticking shutters, mirrors and erratic electrics.
My R8's preview lever was sluggish but for the rest a very enjoyable camera.
I never had a problem with my SL's or SL2 and continue to use an SL with no issues but they had all been cared for and used properly. One SL needed a plastic internal part replacing with a metal upgrade and a self timer relube but continued to function regardless. If you want to use old cameras then buy one thats been used and serviced regularly and any problems will have already been sorted. The R experience has always been hit or miss, nothing new with that.
