So today when going to the movies with a special friend, we (well more so I forced it) "decided" to smoke a joint (my 6th or 7th ever rolled, 2nd one actually filled with herb.) and hotbox my car, 1999 Honda Prelude. Had all three windows closed up, ac off, and my car hotboxed beautifully! Afterwards I just opened up the sunroof and it floated out. My car handled the hotboxing well. Now it stenches of marijuana, lulz. Got coconut air freshener to help with that. Also, the movie was "inception" which was insane, but a different story all-together. Tidbit: I googled pict'd "hotbox" and came up with either smoke-filled rooms, or "hot" women in a boxing get-up
