I am not sure if this is the appropriate forum to post this information, but I was on the Year One website and saw that they have many Legendary and PUI Buick interior pieces on sale as discontinued items. Some of the prices are only slightly discounted while the less popular colors are pretty cheap. A couple of examples I noticed are a pair of assembled PUI brand 1970 deluxe door panels in Sandlewood for $289, and a pair of un-assembled Legendary 1970 deluxe door panels in Burnished Saddle for $269. I called and spoke to a sale rep. who said that Year One is now using a different manufacturer (Distinctive Industries) for their interior upholstery and they are liquidating their old inventory.
