i matched mine up pretty good i think.
from the outside they look the same. but you can pic the difference looking from inside out... but who cares about that
thats an old pic... the tint isnt very tollerant to the law tho.
i have a WRX comapny car as well atm. i had to tint the windows on the front of that. and keep it legal.. can barely notice it on some angles. on others it stands out major.
i guess it comes down to what you can live with. my personal car. i would do what i havd to to get a near perfect match. if you need to keep it legal, you can come pretty close.
good luck with it.
