If you put coffee grounds in your car, won't it just smell like coffee instead of smoke? I guess if you don't mind the smell of coffee that's OK. I have used Nature's Miracle solution to get rid of pet smells, and it works better than Febreeze. I think Febreeze just masks the smell, while Nature's Miracle neutralizes it.
