On the matter of back windows:

I've had four (4) Boxsters.... 2 with glass back windows, and 2 with plastic back windows. I admit that the glass windows are superior for visibility; however, the plastic windows do have the advantage of being larger in size and if you treat them right, they allow good vision to the rear of the car. All in all, I think it's a toss-up.
