Should I leave car windows open when parked in the sun?

I lower all windows to halfway when parked on the drive in full sun and high temperatures. Is this really the best thing to do especially where windows/ sunroof have some degree of tint?

It'll definitely help pull out the hot air and bring in some cooler air. But we wouldn't advise leaving the car as such depending on where you live, because it makes it much easier to steal.
