you can nullify the effects by liberally sprinkling petrified cowdung powder all over the upholstery.
If that still does not do the job - I suggest 10 parts of battery acid and one part water. That should get rid of the offending odor for once and for all.
If you are STILL having trouble, set the damn thing on fire.
If by some act of God the car still smells, call me and I'll buy it and sell it to the Smithsonian.
