-With my CFG set to read only the render stays at the following:

-All I have found that the Cars are static specific to the server you are playing on
-So if you are on one of your favorite servers and you find a car on the next server restart the car will be back at that location but with different attachments
-I placed an apple in a car and moved it 300 meters from where I found it going to see if the items in the car stay with it or if it is wiped

-All you can change the resolution in the CFG then change the file to read only that will lock the file and Dayz will not be able to change it back t the 4k scheme

-This happened to me just now
-WA 2-0 and WA 2-3
-Hopped server from WA 2-6 to WA 2-0 and Lost all my gear except head gear, gloves gun on back
-Grabbed a rain coat and pants on WA 2-3
-Hopped to WA 2-4 and all gear I picked up gone again

I have gotten 3 cars hid them and came back 2-24 hours later and the car is gone.
