Update:
Had the car 3 years now, so we know the effect the desert sun has on black interior. So far, the 5% tint (from 35%, if not stated above) and the silver-grey dash mat have had a DRAMATIC effect on the interior and AC effectiveness. Before, if the car sat in open sun for 1 hr (with windshield shades) you could open all 5 doors, let the breeze blow out the stagnant hot air and get inside & run the AC & has little effect. The black dash would be almost too hot to touch and you could feel the heat radiate from the dash and seats. Now, if you open it up to load the kids inside, the hot air dissipates and the AC is effective. Obviously, this is of no importance to many of you, but those in Sun states may find this interesting.
