It's almost impossible to get these cameras repaired due to the lack of spare parts. But heck, you can buy a spare one for the price of a typical repair! And they hold up quite well. I've taken my ii version on some long wild weather mountain backpack trips without pampering it. It's great to have something that not only works great on a tripod, but that can also be handheld when the wind and sleet are so strong I can hardly stand up in it myself. Yes, you're restricted to a single lens; but it's a third the weight of my Pentax 6x7 with two lenses. And no rangefinder is ideal for long focal length usage anyway. I love the longer 6x9 rectangle, reminiscent of 35mm frame shape.
But repair-wise, I ordered up a copy of the official repair manual and managed to get the thing apart to clean the inside surfaces of the rangefinder optics. Everything mechanical looked pristine. And the taking lens was still like new. And I intentionally wanted a "beater" with a few battle scars already on the body, so I wouldn't cry if it got another scar in the mountains. If I want a pretty camera instead, I already have my mint iii version as well. But a common misconception is that the iii's are in a plastic housing. Nope, same metal die cast housing, and just a different surface coating.
Shutter noise, Ha! Just a little "thwip", and not a KER-LUNK that induces trans-Pacific tsunamis like my P67 does.
