===== Buick Regal (fifth generation, 2009–2017, and sixth generation, 2018–2020) =====
The last two generations of the Buick Regal have been rebadged versions of the Opel Insignia.<ref>{{cite web|url=http://www.caranddriver.com/features/gm-and-opels-strange-love|title=GM and Opel's Strange Love – Feature|access-date=19 March 2017|date=11 March 2010}}</ref> The main differences are the modified radiator grill and the altered colour of the passenger compartment illumination (blue instead of red). The Regal GS is comparable to the Insignia OPC. The 5th generation Buick Regal was first assembled alongside the Insignia at the Opel plant in Rüsselsheim. In the first quarter of 2011, it began to be built on the flexible assembly line at the GM plant in Oshawa, Ontario, Canada.<ref>{{cite web|url=http://blog.caranddriver.com/2011-buick-regal-will-be-built-in-canada/|title=2011 Buick Regal Will be Built in Canada|date=25 November 2009|publisher=Blog.caranddriver.com|access-date=13 October 2012|archive-date=3 January 2013|archive-url=https://web.archive.org/web/20130103115020/http://blog.caranddriver.com/2011-buick-regal-will-be-built-in-canada/|url-status=dead}}</ref> All 6th generation Buick Regals were built alongside the Insignia at the Opel plant in Rüsselsheim, Germany.
