I have a 00 GT, and it seems every time it rains, or there's any dew or condensation on my car, if I crack the window it just pours in. All over the window buttons, lock button, etc. It's almost like it was designed to channel water into my car

Do any of you guys use rain guards? I smoke in my car, and I always crack the window but this is getting annoying. Just wondering if any of you guys could point me to some decent looking/quality rain guards. I've searched, btw.
Also, I noticed since I had my offroad pro chamber put on, every time I stop and idle (especially at fast food joints where there's a wall on my left side), some NASTY exhaust rolls into my car... practically chokes me. Are these short little dates with Miss Carbon Monoxide safe, or should I keep my windows up till I take off?
