One of the oldest automotive brands in the world, Cadillac was founded in 1902 before being purchased by General Motors in 1909. Famous for manufacturing the US car to win the Royal Automobile Club's Dewar Trophy, Cadillac demonstrated that its components were interchangeable during a reliability test. After its initial win in 1908, Cadillac further innovated by incorporating an electric starting mechanism into their production automobiles. This won them a subsequent Dewar Trophy in 1912.

The first automobiles made by Cadillac were the Runabout and the Tonneau, two single-cylinder engine horseless carriages very similar in design to the 1903 Ford Model A. The two-seater Runabout cost $750, the equivalent of $22,619 in current value. Today, the high-end automobile manufacturer primarily makes luxury SUVs, coupes, and sedans. Current models include its CT car series, Escalade SUVs, and XT SUV series. Cadillac’s highest selling year in the US was 1984, with 320,017 Cadillac vehicles sold.

Cadillac plans to drastically change its model lineup in 2023, overhauling one model, refreshing the XT4, XT6, CT4, and CT5 models, and launching two new types of Escalade. They also recently revealed a plan for an electric sedan called the Celestia, for which they've set a price of around $300,000. Cadillac says the car is scheduled to go into production by late 2023, with a plan to fully transition its lineup to electric vehicles by 2030.
