For the 50-year anniversary of the US automotive industry, a big party with an impressive parade was held in the automotive stronghold of Detroit. On July 1, 1946, an opulent parade of the General Motors Group in a dimension never seen before drove at walking pace through the city's main streets. The whole parade was a successful and nice presentation of the big US car manufacturers. Marching bands accompanied the floats and vehicles and provided the musical entertainment.

This fleet's most eye-catching float was that of this unconventional Buick. They fitted the latest Buick front end with a cylindrical rear end onto a huge, wheeled platform. Even if the piggy-packed Buick was real, it was not able to drive by itself, not even for a single meter; as it was just a dummy. But it was a dummy with a special connection.

The front end of the car bore a strong resemblance to a concept vehicle, the so-called "Y-Job." The cryptical abbreviation Y-Job was the designation of the first concept vehicle in automotive history, which was designed by the renowned car designer Harley J. Earl in 1939. It was downright riddled with groundbreaking features.

The Buick concept car, completed just before the outbreak of the war, featured the first electric windows, but this, like the pneumatically actuated pop-up headlamps, was not implemented on the Buick float in 1946. Instead of pop-up headlamps, two standard front lights were fitted. Also, the striking, large, chromed front grill was rudimentarily equivalent to the 1939 version.

The slogan, which was written in large letters on both sides of the parade float, was unmistakable: "When better automobiles are built, Buick will build them."
