1989 was the 25th Anniversary of the Mustang but the Anniversary model didn't come out until 1990 although special 25th Anniversary badges did appear above the glove box after April of 1989. The engine offerings remained the same as the previous year but the V8 got a SEFI mass airflow system. A sporty 5.0L LX with GT adjustable front seats was also offered for the first time as a standard options package. So popular was this LX 5.0L option, the 1989 Mustang model year did not officially end until September of 1989.
