So me and my friends were driving to the fair the other day and I had a bunch of friends with and we started to smell a funny smell that was coming through the heat vents. It smelt like burnt oili and I was needing an answer on what the heck it was. The friends of mine made fun of my crappy car and said tha tI shoudl get it fixed bu ti ahve very little money just like anyone else in this world. What could this smoke and smell be.
