I have 4 bottlecap wheels for sale from my E34. 3 are in pretty good condition and one has some significant curb rash (bottom left). Car drove fine with these wheels and tires did not lose any air. These will make some good winter wheels. I'm not sure how much they are worth, so make an offer. I'd rather sell these locally, because I have never shipped wheels before.
If there is any interest, I will take pics of every wheel separately so you can judge the condition yourself before making any decisions.
