That's where all the 02 guys hang out. Great cars and great community of owners. I miss my 1976 BMW 2002, but those cars rust so much!
Your best bet with the doorpanels is to buy some masonite and cut out the pattern and reattach the vinyl. You can also purchase them for not to much money from a few select places. I think BMW Mobile Tradition remanufactures them but they are a few hundred dollars each.
