Well that is quite a problem. We got my car from a KIA Dealership (a real joke) because it was listed in Auto trader and it was in the best condition and it was the cheapest of any other C we could find. OK, I had the previous owner's registration, but there were 4 of his names listed, and at one time I called 411, but could never get a hold of anyone. So I went to a MB dealer in Riverside (ugh) and got a print out of the MB vehicle history. And there is some damage of something listed at 34,000 miles or something. And it says OWNER IN LINE:5. I really hope that doesn't mean that I am the 5th owner. And when I got a carfax report, it was smog checked and re-listed like 5 times in the 10K miles before I bought it. So I know that my car has some fishy history to it.... but I can't figure it out.

I think today I will remove the door panel and everything and check it out.

Anyone know of any of those insulation pads in the US? That I could buy at say an ACE Hardware??
