The car doesn't smell at all, it is just the damn yellow tint it has left on my headliner that bugs the shit out of me. I have tried cleaning headliners before on my '84 S-10 (bad comparison but nontheless) and it ended up seperating and falling down. Luckily I used thumb tacks and had a pretty cool design going to hold it up, but I don't want to repeat that on my Bimmer.
