"The three cars were jointly developed — still very unusual for GM in 
that era, when each division generally handled its own engineering and 
manufacturing — and shared a stretched version of the new unitized 
Y-body shell used by the Corvair. When the new cars debuted in late 1960 
for the 1961 model year, they were swiftly nicknamed “Senior Compacts.”
