By 1910, Southern Engine and Boiler Works had been renamed Marathon and relocated to a larger facility in Nashville. New models were added to the company’s offering and soon buyers and auto dealers from around the world were coveting their vehicles. While business flourished for several years, the company reportedly hit a wall—unable to keep up with demand (at one time producing 10,000 cars in a year). A consistently changing board of directors and a few unwise business decisions later, the dealership stopped production of their vehicles in 1915, marking the end of an era.
