Hey Frank (@gobuick) is this yours? it seems like the kind of cool performance monster you would build! This thing is probably a blast to drive. https://www.ebay.com/itm/1973-Buick-Riviera/273413249630?ssPageName=STRK:MEBIDX:IT&_trksid=p2060353.m1438.l2649
I think it's a very cool, "different" build. Very musclecar-style for a Riviera. I'd totally drive that one
