I have a used Style 126 rim from my '07 550i. It has a crack and curb rash. Not sure if it's even worth anything, so please make an offer if it is and you have interest.
I would also consider any trade that may have use for the replacement of my 550i, an '08 M5.
So that would be 10W60 TWS oil (or equivalent), transmission fluid, diff fluid, M emblem license plate bracket, or any mod products (however insignificant they may be).

Again, don't even know if this rim is worth anything, and I'm simply throwing it out there to see and maybe someone is in need of a rim and willing to repair it.
This would also have to be a local swap. Don't want to bother with shipping it.
