Everyone is entitled to their own sense of style, and I respect otteud96's tastes. However, I myself would never put a wood-rimmed wheel in a car that has no other wood elements in its interior. It just doesn't fit. Perhaps on a Jaguar with a walnut dash and shift knob. Plus, the rim on that wooden wheel is, well, chubby - the original wheel has a thin, delicate rim that suits the subtle character of the Duetto.
Duettissimo: why don't you tell us what's wrong with your existing wheel? Yea, I know the gold in the hub is faded (see Classic Alfa p/n AC-067). But is the black plastic cracked? If so, as zedsn wrote, it can be repaired fairly easily. Used wheels do come up for sale from time to time; check the "parts for sale & wanted" section of the BB.
