best product i've ever used, which gets nothing but good comments about, from both my friends, and girls, is the Yankee Candle Car Leather Air Freshener. Not overpowering, just subtle enough to give the car that new leather kind of smell...people always ask how i keep my car smellin so new...between using an air ionizer, meguiars odour eliminator, and this air freshener i ave a new smellin car
