Apologies in advance, I do not know much about this wheel. It came on our 280SL. The original came with it, was in poor condition, I had the original restored and swapped back. The wheel is 15" in diameter. No cracks, and is in very good condition. Metal is high polish with only minor surface micro scratches. As for its age, I would guess 12-20+ years(?) I don't know when installed, but car has been off the road since 2006, and also not sure if prior owner, or one before that installed it.
$400 shipped to continental US.
