My ama yesterday went well so I'm happy to talk about more stuff that I know about. While I can talk a decent amount about digital photography most of my experience is with film stuff. I have grown up in the digital era so I may not be as experienced as some of you older folks. I own a few soviet cameras, a chinese one and a couple old cannons. I've used a bit more than that so I should be able to answer a decent amount of your questions.
I may get a Zorki 4k as a secondary camera to have in my car. I hate leaving my Canon F-1 (my main camera) in there as wild temperature swings hurt the lubricant and it's a huge pain to change. Having a weird soviet camera noone has ever heard of with me all the time is hilarious to me, I wanna be that guy who does that.
Oh no the lube in the Zorki would get fucked up too! Don't leave it in the car.
Well, is it any easier to relube? Canon slrs involve a million microscopic screws and springs and stuff and you risk damaging things every time.
