It wasn’t how many units Pontiac had over Buick in the US. It was the transaction price, in which Buick often beat Pontiac.
Of course you’ll see more Pontiac’s than Buick’s. Pontiac’s sold cheap transportation; lots of G3, SV6’s and G5’s that appeal to the working class.
Buick is positioned in such a way that’s the MSRP of its products are much higher and thus appeal to a smaller, more well funded demographic.
