Have this modern males in the ventilation. Each passenger speaks to me in the male. The scent Citrus is wonderful, does not smell like the stuff of cheap car fragrances. I have also tried the vanilla scent (yellow). With the scent you get appetite and reminds me of grandma's baking arts. But red is also the hammer. After real peppermint smells now in my car. So my conclusion: never had a better car scent in use, no longer smells of my dogs and my occasional cigarette.
