Rather than brag about the knockout styling of the '73 boattail Riviera, GM's ad agency decided to push some more questionable "features" in this infomercial-length ad. Like, for example, the new-for-'73 version of EGR, which slashed power while doing very little to reduce oxides-o-nitrogen emissions; when you throw in lower-for-'73 compression, the 1973 Buick 455 had become Fat Elvis. But hey, don't forget Accu-Drive, which was apparently Buick-ese for "really soft springs and shocks." But who cares? We still want one.
