ahh that is wicked i currently use my windows as not to make my car smell too much of smoke n always end up making a right mess down the side of my car in the wind lol
i get all the ash down the side of the car aswell, but it also gets all over the inside of the car.
even i can notice the smell, then again i smoke funny european ciggies so they smell alot and the girl friend does aswell so its like a stale ashtray at times. febreeze works wonders i found tho!
