90 degrees is really no problem. I can have a tolerable interior in five minutes IF I roll down the windows for the first 100 yards or so of motion to purge the bulk of the hot air and I get the car in motion and not stop for five minutes for a congested traffic situation.

Now 108 degrees? That's a different story. But even in that situation if the above situation exists and I can get and keep the car in motion 10 minutes will have me acceptably comfortable.

Have a great day,
