Hello, I am new to the Buick forums, and I posted a question on the interior board about deluxe seat belts. In looking at late 60's to early '70's Rivieras on eBay last night, I noticed that every car that had visible seat belt buckles had the brushed metal buckles with color-keyed belts (deluxe belts). So my question is: Were deluxe seat belts standard on Rivieras of this vintage? Also, was sandalwood an available interior color for '70-'72 Rivieras? Thank you kindly, Eric H.
