The Ottonian Motor Cooperative (abbreviated as OMC, sometimes colloquially referred to as "Ottomoto") is a North Ottonian automotive retailer. Specifically, it is a seller's cooperative for North Ottonian automakers to join forces and coordinate their efforts when selling North Ottonian-produced motor-vehicles abroad, provide service and customer support for such vehicles abroad, and coordinate and unify efforts between automakers for purposes of national defense or security.
Currently the Cooperative coordinates the efforts of Svaartaron Auto Works, Jormundkaar, and SEDA. Between 1974 and 2000, it also included Vulksmotor, but since 2000 the federal state-run automaker has marketed its products abroad independently.
As of 2001, OMC has been used to partner with the Rezese automaker Panther Autos to bring affordable electric vehicles to North Ottonia.
