At first, I thought... you know... the reflections look cool in the car. But in this picture, it really doesn't. The polarizer makes the shot look so much better.

Thanks for sharing that image. I actually kind of argue against polarizers, because I always think.. Ill just do it in post process... well, this would take a whole lot of time in post process to fix for one... for two, the image is just plain better with the polarizer.
