Dealer says they have removed carpet and no holes have been found in the body of the car, stains must be because of calcium on Winter boots. The stains are everywhere, even under both front seats??? Could not put my feet there even if I tried... I have a passenger only on rare occasions, so the stains should be less apparent - but they are the same for both sides. There is a clear humidity problem. Am not satisfied with the way this was handled; am worried that rust will build up later on. Am sure other people have experienced this, with this car or any car... any advice would be appreciated! Thank you!
