Oh, they are recognizable)
Except little cars.

If they are at lease a little recognizable despite the modifications, they can be listed as they original were (e.g. recognized by windows, pillars, etc.)
But if they have a full new body, "made for movie" is better.

And here we go http://imcdb.org/movie_972558-Obitaemyy-ostrov.html
Finally, we have a brave contributor whom didn't afraid of this movie and made it for database.
So main problem is how to list a vehicles which is obviously based on known models?

I find that funny, we all know that truck iz MAZ, despite its heavy makeup.) I think it's 535. Bus is definitely 677.
That pink "hunter-killer" is BTR, of course, not sure 70 or 80. Both kind of tanks are T-64 (such a waste of tanks!) and yellow mobile transmitters are BMP (1 or 2)

So. I did few snapshots
Some MAZ
LiAZ 677 i think
That gullwing doored car
Aliens Tuk-tuk
Some yellow tricycle
Blue ugly thing
Rusty SUV on background

Oh, yes! Pink tank!

In the book it's clearly mentioned, that some aged characters reminds pre-war times. And I think that this dialogues were transferred in movie too.

That was cool cyberpunk styled car.)

I think its like in Equilibrium, the war was long ago... or something.
I can't find picture from behind the scenes of OO. There was a customized gullwing door muscle with piece of wood to hold door open

Well, at first I was irritated by fact,that altough story is set in post-nuclear world, there is almost no clues for that (except for town of mutants). Capital is depicted as huge metropolis with skyscrapers, but how can they survive the war? I'm sure that such a big city will be nuked for sure.
