context_page_description: The first Cadillac automobiles were the 1903 Model built in the last quarter, 1902. These were 2-seater "horseless carriages" powered by a reliable and sturdy 10 hp single-cylinder engine developed by Henry Martyn Leland and built by Leland and Faulconer Manufacturing Company of Detroit, of which Henry Leland was founder, vice-president and general manager.
  Reformed as the Cadillac Automobile Company in August 1902, it began manufacturing the runabouts and named them "Cadillac" after the city's founder Antoine Laumet, the self-styled Antoine Laumet de La Mothe, sieur de Cadillac at the re-purposed Detroit Assembly. The 1904 Model B was a refinement of the 1903 and while still a mid-engined, one cylinder automobile, it now had an extended front and transverse front suspension. With the introduction of the Model B, the 1903 style became known as the Model A. Both the Model A and B were available as a two-passenger runabout or four passenger rear tonneau. Catalogs also show a light delivery.
  The one cylinder Cadillac continued to be offered through 1908 in the runabout, tonneau or delivery bodies under a variety of Model designations which are delineated below.
context_section_description: Cadillac's single-cylinder lineup was consolidated into two models for 1906, the short wheelbase Model K and long wheelbase Model M.  Priced at $750 for the Model K or $950 for the Model M, 3,650 units were sold that year.  The K and M were essentially similar to the Models E and F from 1905 but with updated bodies.  Production and sale of the Models K and M continued in 1907 in both the Tulip and straight lined body styles.  The  Model M was offered with a delivery body in 1906 and again for the 1907 model year.
  Three 1907 Model Ks were used in the famous Dewar Trophy test of the Royal Automobile Club in England.  They were disassembled, the parts mixed, and then reassembled without problems.  This test cemented the Cadillac's reputation for precision and quality and brought fame to the marque.
  The Model M continued only as a commercial delivery vehicle for 1908, priced at $950.
