For headlights with HID, they are all going to be expensive as they are all OE from Hella and a few other companies. You can buy used ones on eBay, but not in the best shape. Also for the HID, you will also need the ballast which is typically not included with the used housings. Not sure about the pre-LCI e60s, but adaptive headlights are also more common in US LCI cars than just straight xenon, so you'll want to make sure you are ordering the correct part numbers. Not sure how much damage you are recovering from.

There are a lot of companies online (with which I have no experience) that will sell you a painted aftermarket bumper. As an 18 year old car, though, it will not match that well. The first one I looked at came up with $280 painted.

Also, this forum is pretty inactive relative to the 3-series forums. I check here from time to time, but 5series.net is a more frequented.
