you can get a few types of glass for sides and rear glass,
Security glass, which is pretty dark usually blackish and is only on the rear,cargo and rear doors, front doors are left clear
green tint, hard to notice unless you put a sheet of white paper behind it
bronze tint, not that dark but you can tell its on there
clear,
all tints are in glass
what ever your side glass is your rear window will be the same, The stagea's came out with green (i think) or security glass if the rear has been tinted
with after market tint and they are removing it make sure the dont stuff your demister wires.
I hope that makes sence!! and helps
