Hi,
Do a bit of research about any Leica camera and you'll find a list of things that go wrong.
The CL gets its share but, like the M5, it's not a mainstream model and that's a crime to some. F'instance, you'll notice that no one moans about the M2 not taking more than a 90mm due to the frame lines but it's a dreadful matter with the CL.
Others expect the camera to be bomb proof, as though all the others are but they aren't.
And the meter needle can be seen, unlike scales and so on beside LED's. And you can change the shutter speed and see the range changing in the VF. And you can feeel the rewind handle turning without much effort, instead of having to look.
So my 2d worth is to say get the CL and its two lenses and you won't go wrong if you read the manual about metering and battery checks. It might also stop you hankering after the M6; as will reading about those dreadful M6's elsewhere on these forums.
Just bear in mind that it's a 1970's camera and use a bit of sense. If the worst happens it will be repairable and there are specialists who can help, just like any other Leica (except the minilux when the worst happens).
BTW, I've had a second-hand CL and still have it and still use it. It was the first second-hand one I could find many years ago and there were still new ones in the shops then, so I was lucky. And it meant I could afford the 90mm lens as well. Both lenses are up to Leica's usual standards and genuinely loved by people who have owned and used them. Search on the 40mm Summicron and see what they all say on RFF...
And I've never had people spit at me when they saw it, ever. Although you'd expect that from reading some of the comments.
I've also owned a CLE for a week, bought new and returned many years ago. (Having to switch it on and remember to switch it off again irritaed; unlike the sensible system of the CL.) I'm not so certain that they (CLE's) can be repaired but the 28mm lens sounds nice and could be added to the CL one day.
