Kristo, Your post is stale, but if you’re still seeking advice, here my ‘02 cents worth...
Decide if you want to sell/negotiate direct to a private party or auction it through a third party.
If the former, consider posting ads on local/regional bmw enthusiast sites (such as this one, BMW CCA, bimmerforums), followed by larger audience sites (such as Hemings).
If the later, consider Bring a Trailer, where ‘02s regularly come up for sale and past sales/prices are archived to help both buyers and sellers determine market pricing. Read some of the archived auctions to get a sense of the questions and comments the BaT community can throw out there (it can be a tough crowd, especially for sellers who don’t make full disclosures on their cars) In either case, it will take time and effort on your part to get the best price for your car.
Another option is to attend the BA02 Swap and Show in May and put a 4Sale sign on it in the swap meet lot or on the show field.
Have you tried to sell or sold your car yet?
