Now, please correct me if I am wrong, but isn't the point of having an air freshener in your car to help keep the air smelling fresh? I got a freebie air freshener (I can't even remember where I got it) and today I opened it up and hung it off my rear view mirror. I went back into the car a few hours later, and all I can say is P U.
That damn thing smelled like a cross between stale gingerbread and burnt marshmallows. WTF??? Now that smell is forever embedded in my brain. And my car doors have now been left open overnight in the garage, in the hopes that it airs out before I have to drive in the morning.
