make your very own carbon filter for $25 bucks. ELIMINATES ANY AND EVERY SMELL. PERIOD.
there use to be a good thread on it at overgrow.com before the site was shutdown. I've made one and it works wonders but it's hard to describe it without pictures.
You could always go to your or your friends car?
I always used the two fan method.
What you need:
Window Fan, box fan, dryer sheets, paper towel roll, towel, incense.
Open window put window fan in, make sure it is blowing out on high. Towel the door and set up the box fan in front of the door blowing towards the window use on low or meduim. Put a chair in fom of the fan with incense on it buring. Make a spoof (dryer sheets in a paper towel roll). Sit by the window and smoke till you can feel your legs.
This always worked from me, make sure you either zero the hit or blow it into the spoof near the window.
