What is OMC?
OMC is an independent US-based auto club, that specializes in German-Made 1968-1975 Opels.
(Opel GT, Opel Manta, Opel Kadett, and Opel Ascona & Wagon) originally imported by the Buick Division of General Motors.
OMC was founded in 1980 in Southern California by a group of Opel performance enthusiasts, and since has remained a source for information that is truly independent of any Opel parts or service vendor.
The OMC "Highlight of the Year" is the "Opel Nationals Event" held every Summer at selected locations across the country.
OMC has published our newsletter "The Blitz" since 1981, and is the only US Opel club that is officially recognized by the Opel factory (based in Russelheim, Germany).
