MINI Cooper is a red car the Simpson family rented when they were in London. Unfortunately, they got stuck on a roundabout. After driving in circles for hours, Homer decided to break out of it, plowed straight through the gates of Buckingham Palace and slammed into Queen Elizabeth II's horse-drawn carriage.
Homer, Lenny and Carl once imagined themselves racing through the Springfield Nuclear Power Plant in MINI Coopers. In the vision, Homer and Carl had an accidents during the race and the their cars blew up, making Lenny win the race.
