You are an idiot and I the fool for playing with an idiot.
Note to anyone else reading this: A car that was owned or operated by a smoker is likely, based on many personal observations, to have been used abusively.
That is why I am very shy of buying any car, no matter how good the deal may seem, where it is obvious the driver was a heavy smoker. In my experience it was always a mistake, because the damage smokers do to cars through abuse and negligence is expensive to repair.
Maybe if they were smoking crack, yeah then, but I don't see any correlation otherwise.
1) I did not disagree with the rest of your list. Several good, smart points there. I'd listen to most of your advice as written in your original post.
2) I am obviously a smoker. No "smoking out" required.
3) If I were not a smoker, I would not want to buy a car from a smoker simply because of the smell. It lingers for years. The smell of mildew would overpower the smell of smoke before I could ever get rid of it.
4) I've owned and driven nothing but new cars (first owner) since 1995, and I have never, ever smoked in any of them.
I need to go offline for a while, so I'll check in later....
