Between the years of 1973 and 2004, the General Motors division of Buick produced a medium sized automobile known as the Regal. It coincided with the Buick Century, another mid size car. The two often shared power trains and bodies throughout this period.
While Buick may have been the first division of General Motors to bring a personal luxury car on to the market thanks to its Riviera in the year 1963, the division was also slow to react to the development of the lower priced mid size personal luxury car market. This market had been created in the year 1969 with the Pontiac Grand Prix and was followed up the following year with the Chevrolet Monte Carlo. At around the same time, Oldsmobile added a formal notchback coupe to its line up known as the Cutlass Supreme.
Looking for a way to compete with the above cars, Buick decided to introduce the Regal in the year 1973. This year also marked the introduction of General Motors’ first major restyling since the year 1968, which the Regal certainly benefited from.
In the year 1978, a downsized Regal appeared. It came with a new version of the traditional Buick 231 cubic inch V6.
