Whats the value of a coach that has been smoked in vs not smoked in?

[Nara Queen]

We have looked at quite a few motorhomes that have been smoked in. Most coaches have not been smoked in which is good because we are not smokers. I am not turned on by the yellowing from a coach that has been smoked in. Is it that easy to remove the yellowing? and what about getting the smell out? is it worth even trying? Or should we skip coaches like this and move on to only ones that have never been smoked in? If it's not that serious and we can remove the yellowing and smell or even have professionals clean it up then we may still be interested in purchasing a coach for the right price if it had been smoked in. If we were to hire a professional what would it cost? So many questions! Thanks for all your help! Hope everyone is doing well.
