I have to say this option was my least favoured one but it came with a pack I was getting anyway. I have to say I really like it now. There is a really pleasant scent in the car that is not overpowering like air fresheners are. It almost just keeps that 'New Car smell' persisting for longer.
Thumbs up BMW!
