Argh. I am apparently one of the vanishing few who bought their cars new, and assumed your car would still have its original interior.
Can you find any part numbers on the damaged panel, or if it's missing, one of its mates: to help identify the color? The one you want may not be ENDED.
Perhaps if you post some pictures of the matching panels, someone can identify the fabric and color. For reference:
- SCHW = schwartz = black
- ANTH = anthrazit = anthracite (a very dark grey)
- GRAU = grau = grey
These were the original colors: both SCHW and ANTH will bleach over the years.
