No kidding, its called "The Greenhouse Effect". It doesn't help cool the car, it makes it hotter. I thought the purpose of the translucent roof was so we could see while we are in the back during the day.
I also disagree that Pullman Brown hides dirt. It doesn't, my P7 got washed about six times last year. Since the company doesn't want to pay the Car Wash to wash all the cars anymore. Why don't we just start painting the cars Tan or something. The dirt wouldn't show up so bad then. I'm embarrassed to drive around in a filthy Package Car all the time.
