I am sure that it makes a difference but it looks terrible and the idea of taking it off every time I want to use the back seats for some strange reason is annoying. I will wait and see how bothersome the wind really is without or with the windows up.
Absolutely. the rear window does not much. If you have someone in the car and you want to carry on a convo, you will see the major difference it makes. If you're a loner and don't car, its fine. It also helps when its cold out, you can drop the top, keep the windows up and put the heat on.. and roll.. so so MUCH fun.
