go to ebay for real in-market norms
You can probably get something for them but not 1000
The cool thing about e36, e46, and e90 wheels is that they are typically interchangeable (provided you're not trying to put these on a 330i, brakes are too big)
You need someone with a 325i sport who wants winters, problem is the all seasons aren't worth much to them.
I paid $500 for some e46 16" take offs I would think you could get more than this? The other option is to store 'em and sell one by one since you may appeal to a pothole victim! You can get $200 a piece with the tire?!?
