Bought used yaris, smelled nice, now bad. Any help?

[Shinare]

I bought my used yaris about a month ago and it smelled really nice on the inside. now that its a month old the nice smell has warn away and, as an ex-smoker, I can tell this was a heavy smokers car before me.

Aside from feeling like I was hoodwinked with "new car smell" from the dealership, is there anything I can do to permanently "fix" the smoker's smell?

I'm willing to gut the car and wash everything if that would make a difference (or is even possible or advisable).

Any suggestions? Its starting to get warmer here and just having open windows is getting to be out of the question. I'm sure when I have the AC on and windows closed %100 its going to get even worse.
