Speaking of cigarettes…..

Depends what the car is, 440 dart, I'm buying if it smells like Gorilla farts. I'm an old smoker of cigarettes and kind of like the smell, from a distance. I think broccoli smells a little like cigarettes, :D but that's me. when buying something, I always go through my car's interior with pro cleaners, and have gotten rid of many odors in them. I would not walk away from a great deal because of the smell.
Unless there was a dead body in the trunk or back seat, I'm not worried about it. My current daily driver had a nasty odor in the interior when I bought it, but at the price I paid, it was the least of my concerns. I pulled everything except the headliner and cleaned it all with a carpet and upholstery cleaner. Took one Saturday afternoon to get it done, and over 2 years later the smell hasn't come back.
