I use Four Star's leather scent in my car. mmmmmm.... nothing like the smell of leather. On client cars I like to use Ozium's New Car Smell. Its the closest thing to actual new car smell that I have found. Its hard to find a scent that isn't objectionable to people. I've never had a problem with that one. My other favorite is Meguiar's Odor terminator. That one kills smells like nothing else. The scent isn't too bad, but I have had people tell me that they don't like it. I like it, so I guess its just a matter of preference. It is awesome at killing bad smells though. I use it for cigarette smoke and other really strong smells all the time. Odor removal is a little different than just spraying a couple shots of something nice in the car, so i don't know that I would use this product just for the scent, but it really isn't all that unpleasant if you do use it for that.
