This is my 2002 325Ci

This is my 1998 316i Compact which I am preparing to sell it has around 181,000 KM on it.

So a few questions!
I am looking to replace my blacked out grill on the 325 with a stock (or stock looking) chrome one. Where can I purchase one at a reasonable price? Is there someplace (or someone) where I might be able to trade my blacked out grill for a chrome grill?
Whats the best way to go about selling my old 316 compact? I still have a few things I need to do to it before I am ready to sell it. I know about auto24, but outside of that where else would be good to list it?
What is the best way to get parts out here? Are there any websites I can order from that have better prices then local parts shops in Tallinn?
