https://portland.craigslist.org/clc/cto/d/65-buick-riviera-gs/6313785897.html I am from Post Falls where this car apparently sat for years. Wasn't a big town back then, not sure how it hid out for so long.
I believe the rims are 71 and later #895's. I know 65 rims are very very hard to find but for that kind of money it should have them.
I saw on the Riviera board that one member mentioned it has standard seats and deluxe door panels, so one or the other is wrong......
