I'm selling a trailer hitch off my 96 318ti. $200 with shipping included for the lower 48 states (anywhere else and your paying). If your mechanically inclined, it isn't too hard to install yourself. Just requires removing the back bumper and drilling a 4 holes in the car. I prefer paypal, but will accept a money order.
Here is all the technical mumbo jumbo:

It can tow 1366 lbs with a 165 lbs tounge weight as listed in the european owners manual. The Da'Lan hitch is limited to 150 lbs. tounge weight though. I have one on my car, but have yet to tow anything. I plan on buying a small enclosed cargo trailer in the future.
