Hans G. Ritter founded our company in 1974. Hans was born, raised and educated in Germany. Upon moving to the U.S. he began working out of his home in Oak Park, Michigan repairing motorcycle and marine speedometers and gauges. His small business grew steadily and was later incorporated under the name of "Specmo Enterprises". After Hans retired, his two sons purchased the business and now manage and control Specmo.

Over the years, Specmo has developed into a financially strong organization that has gained a reputation as a pioneer and innovative leader in the automotive electronic instrumentation industry. We are one of the nation's oldest and largest service & exchange centers for GM electronic instrument clusters and Delphi-Delco radios.

Our corporate headquarters and electronics technical center are located in Madison Heights Michigan, a suburb of Detroit. This is our wholesale facility whose primary function is providing service to auto dealerships participating in ACDelco instrument cluster and radio pre-exchange service programs. We also offer some limited services to private sector jobbers. Our business philosophy is to focus on the customer (vehicle owner) and the dealer body that supports them.

“Never forget our origins”
