Opel Monza features and equipment

Features shown below are tied to the available source material for this model. Equipment can vary by year, trim and market.

Standard or documented features

✓Opel's own four-speed manual gearboxes were not up to the job and, instead of putting in a more modern five-speed manual gearbox, Opel turned to gearbox and transmission producer Getrag, and installed the Getrag 264 four-speed manual gearbox in the early Monzas

✓It handled well, thanks to the newly developed MacPherson strut system for the front of the car, as used on the Rekord E1 and E2, and the new independent rear suspension gave the car soft, yet firm, driving characteristics and excellent stability for such a big car

✓The cars all were marked as "S" models on the front wings, and came with 15-inch Ronal alloy wheels and a 45% limited slip differential
