Well, Buick is a very prestigious nameplate in China. It would make sense for GM to make some Buicks in China even if it were only for Chinese consumption.
“Buick is a very prestigious nameplate in China.”
Back near the beginning of the twentieth century, there was a race across Asia, and it was won by a Buick. I guess that lore has been handed down to the present generation.
They rejected the Buick name Regal, though, because Communists supposedly squirm at the mention of royalty, but in actuality I think it’s just politics.
