Driven by the need for post-WWII affordable transportation and restrictions placed by post-war agreements, in 1955 BMW decided to supplement slow sales of their larger models with an inexpensive car. BMW acquired the license from the Italian refrigerator manufacturer ISO company to make this “bubble car”–the Isetta. Minor changes were made to the styling in the 300 model, and the Isetta 250 engine was replaced with one from a BMW r27 motorcycle. Even though the Isetta has 10" tires, weighs less than 800 pounds, and goes from 0 to 30 in 11 seconds, mechanically it is a very reliable car. You will notice this car has one door; it seats two passengers. Many Isettas survive to this day.
