1975-1981 Opel Manta B1 I never cared much for the Manta B until recently. Styling was too clinical for my taste. In retrospect, the pre-facelift Manta B's didn't look bad at all actually. The 1982 facelift (B2) with the body cladding and heavy looking plastic bumpers is a bit overdone though. The car was in production until 1988. Opel publicity photo found on the internet.
