One of my favorite car designs of the 1970s is the boattail Buick Riviera. This personal luxury coupe with its unique tapered fastback roofline was made between 1971 and 1973. It was a fresh departure from the odd-duck '70 that looked like a fatter version of the now dated 1966 model. The '71 Riviera's pointed prow and forward slanted front, and rear roof reminiscent of the C2 Corvette set it apart from more conventionally styled big coupes. The sharp styling was diluted somewhat on the 1973 cars, which wore a bulky front bumper with wraparound turn signals incorporated into the headlamp bezels, and the jutting point on the rear end was dumbed down to almost nothing.
