About the marque
Ema is present in the NHTSA make/model registry with a Limo entry, but the accessible record does not establish a reliable manufacturer biography, founding date, country, vehicle class or production chronology. The catalog preserves the exact identity and does not merge it with Ema Motorworks, event and measurement companies using EMA, or unrelated limousine builders. A more specific history would require a primary manufacturer record or period documentation.
