When the final generation of the Regal debuted in the spring of 2017, sedan sales were already in decline, especially for Buick. Even back then, it had been a long time since the heyday when Buicks littered the bestseller lists, and Buick sedans were stuck with low sales figures. For the final two generations of the Regal, Buick took it sportier (and saved money), by essentially re-badging the European Opel/Vauxhall Insignia. For enthusiasts, this was good news, with sharper handling and leaner styling that aggressively shook off the old stereotypes, and likely turned off buyers of the previous generation at the same time.
