9. Cadillac Catera / Opel Omega
The Cadillac Catera brought European flair to American luxury showrooms by rebadging the Opel Omega. Built in Germany and shipped to the U.S., the Catera offered a unique blend of agile handling and comfort, standing apart from traditional Cadillacs. Despite its new badge and a few luxury upgrades, the Catera’s European roots remained clear, providing a distinctive option for buyers seeking something different in a midsize luxury sedan. Source
