C H O P — The Riviera nameplate has been used on Buicks since midway through 1949, first used to denote the new pillarless coupe bodystyle. It went on to be used on several Buick 2 and 4 door pillarless card in the mid '50s, finally becoming a personal luxury coupe in 1963. Though the nameplate has not been used since the mid '90s, my Riviera would become, once again, a unique top-of-the-line flagship for Buick, a 5 door sport hatch. Powertrains would be top-shelf hybrids with AWD. This chop began as a photo of the less than svelte BMW 5GT.
