Just got back from Carlisle PA Car Event and finding used or new Buick parts there are almost non existant. But I did find a company called www.profitautointeriors.com that have stepped up and have parts for Buicks, much like Legendary Interiors, but their cost are much lower without sacrificing quality. I ordered a new interior package, less seat covers from them at half the cost of a Legendary package and will be delivered within 2 weeks. Their website offers much more. Check them out...
I suspect you have a reseller. There are only two companies that make interiors for these Buicks. The best quality interior is Legendary. The other company is PUI out of Tennessee. My money says you will receive a PUI made interior marked up between the wholesale and retail price.
Not according to what they told me. They claim to have dies from GM for their interiors and replacements. But then again, thats what they say. The carpet that I ordered is a ACC brand. The door panels, they say are made for them with the correct material and look as the OE. I'll know better in 2 weeks, but the cost was the difference. I paid $378.00 for all four door panels including the arm rest covers for a convert. Plus $160.00 for the carpets. The window fuzzie kits, all 8 pieces, plus two arm rest bases and the pads were around $250.00 Price out a Legendary comparable, you will be surprised the difference. Legendary was there.....and thats not saying much about them. They had a book you can order from, no samples, no parts there just a few suits sitting at a table of catologs.
When you click on a part, say a 67 GS door panel it dose say "Manufacturer PUI" and says how much you save over list price. It still seems like a good place to get everything you need for your interior in one place and the price seems good.
I haven't compared Buick stuff yet, but the 66 Pontiac GTO front seat covers are $45 cheaper than Legendary.
These are the folks who found the NOS fabric for my dark brown vinyl roof. Whether they stitched it themselves or had someone else do it, I can't say. Customer care/communication was excellent, product was perfect. Price was not a lot more than one from any repro. catalogue for a black or white roof. Met them at Fall carlisle a few years ago.
