Overall Rating
Opel Commodore:
The Opel Commodore is an executive car produced by Opel from 1967 to 1986. It is the six-cylinder variant of the Rekord with styling differences. The Commodore nameplate was used by Opel from 1967 to 1982 in Europe and to 1986 in South Africa. The Commodore nameplate was adopted by Holden in Australia, where it continued until 2020.

C Overview:
Opel Commodore (C). With 185 Nm of torque, it offers ample pulling power. Weighing only 1200 kg, it’s quite light. Rear‑wheel drive offers dynamic handling and sporty feedback. Acceleration is relatively slow (0–100 km/h in 11.5 s). The top speed reaches 180 km/h. A four-door car with a separate trunk, ideal for families and daily commuting. Seating for 5 makes it ideal for daily use.
The Opel Commodore C was produced before the establishment of Euro NCAP in 1997, and therefore, it was not subjected to modern crash safety assessments. Safety features are basic by contemporary standards.
