25. Buick Regal GS
For decades, Buick didn’t have a proper muscle machine and in 2012 it came from an unlikely source – Europe`s GM division Opel. Buick started selling rebadged Opel Insignias as Regals and amongst regular versions, the company offered a performance model called Regal GS. The stats were pretty good and drew a lot of attention of car aficionados. Under the hood was a 2.0-liter turbocharged engine with 280 HP, 6-speed manual transmission and all-wheel drive. The combo proved to be fantastically capable in real life and marked the return of Buick performance.
