I live in sunny California. My Passion is black on black. So it's a heat magnet, but with the pano-roof sunscreen closed, a good solar-shade for the windscreen, and cracking my windows about 1/4 inch, the interior of the car stays relatively cool. I'm tinting my rear window and the two smaller side windows as dark as I can get them here shortly, so that might help a little more. Also, with black leather seats, I throw a white towel over the seat and steering wheel, when I'm going to be out of the car for a while, and it's scorching outside.
But all that is just when the car is parked at work. Although most of the time I do find some shade.
When at home, the
smart is garaged. So no heat issues there.
