MX is a very reliable camera. However, there are a few common problems that I have found on several MX bodies. Most are result of storing or using a camera in harsh conditions (dust or humidity), or handling or servicing camera improperly. If you find a good, clean MX that has been properly used and stored it is very unlikely you will find any of these problems, but here is what you have to pay attention at:
Visual shutter speed indicator in the viewfinder not in sync with shutter speed dial - that means that someone has disassembled and reassembled camera incorrectly;
Visual shutter speed indicator in the viewfinder not working at all - that means the cable is broken;
Metering seem to be off with some shutter speed dial positions and LEDs showing wrong reading or erratically flickering - camera requires cleaning; (Note: test this at ISO/ASA 100 setting - MX does not have full range of metering at all ISO speeds - for example metering ISO/ASA 200 and 1s will not work, ISO/ASA 400 and you loose metering at 1s and 2s and so on. So lower red LED will indicate "underexposure" at high ISO/ASA and slow shutter speeds. This is not a fault, it is BY DESIGN.)
Metering can not be turned on with half-depressed shutter release (works only when fully depressed) or the opposite, metering can be activated with very light touch on shutter release or even when shutter release is locked, which can drain batteries in days - fortunately, this is very easy to fix since meter activation contact can be accessed by simply removing the bottom plate and easily adjusted.
DOF preview not forking;
Self timer not working;
If you want to avoid most of problems MX may have consider ME Super instead which practically eliminates the possibility of all mentioned problems except for the self timer problem.
