Badge engineering is a common way for car manufacturers to expand their lineups without significant investments. All they need to do is take an existing car from a different, often affiliated manufacturer, and put their badges on it. GM is one of the worst offenders when it comes to badge engineering. Which one of these manufacturers did they frequently "borrow" cars from?
Answer Opel
The German brand Opel was owned by GM between 1929 and 2017. As a result, many Opel cars were badge-engineered to be sold under different GM brands in different countries. In the US, the Opel Insignia sedan became the Buick Regal, while the Astra hatchback was sold as a Saturn.
