The Northfield Police Department used the 1976 Impala patrol car, which was introduced that year using the 9C1 code still in use today. The 1976 Impalas used a previous year Caprice nose, with a new "egg crate" grille insert. The Impala had round headlamps while the Caprice used the new quad rectangular ones. The Impala was more of an entry level vehicle for fleet usage, especially with law enforcement agencies. The Impala was discontinued in 1985, and brought back in the early 1990s.
