I had my car in for routine service. When I got it back it smelt like a sewer. I narrowed the smell down to the car seat that I was sitting on, it was horrible, smelt like a fart mixed in with sewer water. I rolled the windows down but it was of no use. Good thing I have a steam vac, I had to steamclean it for like a hour but finally got the smell out. I purchased a car seat cover and I put it on the car whenever I get it serviced now. If it happens again I can just clean the seat cover. It would have been terrible if I did not have that steam cleaner though.
