This is sooooo easy to choose.
TINT! For every car I have owned, a tint job is done within days of getting the car. I would never go around without a nice tint. I'm not sure what bad experiences others may have had, but twice I've had tints done in the winter(the Trep was done in Feb) and had no problems. The quality of the installer makes the difference. And finally, there is NO tint law in Ontario. Get it done now, 5% all around, before the legislature passes a tint law.
Plus, for your 3 choices, you could do the tint and front seats for the price of the RB1.
