Sander or DA marks in the front wheel well around the triagular bracket in there (bracket is on top front of ww). I do and am wondering if this is correct from the factory. I inspected the car and it definetly does not look like it was hit or has any body work on it. I assume this was done at the factory. It is only on the driver side. I also noticed alot of chalk marks etc all over from the factory when looking under the car while up on my Kwiklift. I keep meaning to get under there with a camera and document this stuff. I am sure somebody would love to have them photos in 30 year. I had posted this on the Z06 site but figured it was more of a C5 thing than a Z06 thing so am putting it here also. Thanks.

I've seen the chalk marks but I haven't seen the sander marks you talk about. I'll have to pay closer attention the next time I'm under my car.
