I took a bad hit from a rock today, and need new glass. Should I go to the dealer or a glass shop? Insurance is picking up the bill, so the difference in price is not a factor. I'm worried about a couple of things though. The first is rain sensing wipers, and the second is the gap between the glass and the panels that our cars have. I'm not sure how common this is, or if it's an issue at all.<p>Where would you go to get it done?
