I have a 2001 9-3 with the same problem - actually within 3 weeks of
buying the car I took a rock through the left headlight lens as well as
the left foglamp (thankfully no shots to the hood).  I ordered a
replacement headlight lens right away, but I've held off on the fog
lamp thus far. Every once in a while you'll see one on ebay (looks like
they go for about $60 or so). Eeuroparts.com has them for about $140.
