Creosote and petrol for me too! I used to love the smell of nail varnish but have gone of that now. Fresh baked bread and coffee beans. Oh and my hubby's aftershave - well the I got for him anyway!!
Gin - which I don;t drink by the way and ... brace yourselves ... maggots! They remind me of my Nan when she used to take me walking by Barlaston Pools, and the fishermen always had maggot boxes, and I have loved the smell from that day to this.
