i've never had a problem with any of that stuff. people have smoked in my car (alot) and it's never smelled like smoke. not even 5 minutes after. :dunno: and there a ton of stains in the carpet from the previous owner so i'm not too worried about that either. i do need to get them out. i'll do it eventually. but i eat and drink in my car all the time. but i also spend more time in my car than anywhere else.
