This 1973 Buick Riviera, owned for 25 years by its current keeper, was modified in the style of the Silver Arrow III concept car. The modifications include a silver paint job, Sweepspears, Silver Arrow badging, and a GS-style air cleaner, accompanied by a custom two-piece front bumper. Now located in Casco, Wisconsin, this distinctive Riviera has been featured on Bring a Trailer with an active bid of $4,250.
