This is driving me nuts...every time my car starts to get any sun on it, it starts to smell of choof. Now it didn't worry until I had my mum in the car on a sunny day a few days back. It just kept getting stronger and stronger til she had to say something. I explained I couldnt find any in the car anywhere...so once again my car was searched thoroughly without success. Its soooooo strong. Its a nice smell mind you, but shit I got kids I can't have my van smelling like dope, I been making 'em squash in the other car. Ive tried spray, steam cleaning...it won't go away, there must be smoke in somewhere, I just can't find it.
