Opel introduced in 1999 a final facelift for its largest car from the European market, the Omega, trying to save its sedan from extinction.

Omega is the last letter of the Greek alphabet and was the last attempt made by Opel to compete against the other German premium carmakers.

Opel introduced the Omega lineup in 1986 as a sole replacement for two ranges, the Senator and the Rekord, relaunching its competition in the mid-size sedan segment.
