In the early 1970s, Ford Motor Company was producing the Maverick, a compact car marketed as an affordable and efficient vehicle. However, the demand for the Maverick was not as high as Ford had anticipated, and they found themselves with a surplus of unsold cars. To deal with this surplus, Ford decided to store thousands of unsold Mavericks in the Subtropolis caves located in Kansas City, Missouri. Subtropolis is a man-made underground complex of limestone mines, covering over 55 million square feet, and is home to many businesses that use the caves for storage and other purposes. Ford leased about 25 acres of the cave complex, which was ideal for storing the cars as the caves are naturally climate-controlled with temperatures ranging between 60-70 degrees Fahrenheit year-round. The cars were kept in the caves until they could be sold, which reportedly took several years. The storage of the Mavericks in the Subtropolis caves became somewhat of a legend in the automotive world, with many car enthusiasts and historians fascinated by the idea of thousands of unsold cars sitting underground for years. Today, the Subtropolis complex is still in use, and while the Mavericks are no longer stored there, the story of their time underground remains a unique piece of automotive history.
