The VN is larger than the previous VB-VL models, making the interior space competitive with the EA Falcon which was similarly released in 1988.
The styling is based on the European Opel Omega with a stretched floor pan from the VL while the engine and transmission were developed from US designs. This amalgamation came together surprisingly well and the VN won a car of the year award in 1988.
The Executive is the entry level model and power steering was standard equipment along with an AM/FM radio, tinted windows, intermittent wipers and driver's seat height adjustment.
Air-conditioning and automatic transmission were popular options, particularly with fleet buyers.
The initial quality glitches with the Commodore spurred GMH into introducing a program of running changes and improvements, most of which were in place by 1990.
The 3.8-litre V6 did not follow the multi-valve fad and used pushrod operated valves and cast iron for the major engine components.
The power output is 125kW with very strong low down torque. The engine had major revisions in 1990 which reduced engine noise and vibration and improved fuel economy.
A five-speed manual transmission was standard but most buyers opted for the four-speed automatic which has a lock-up torque converter.
The suspension uses MacPherson struts and coil springs at the front with a live rear axle and coil springs at the rear. Anti-roll bars are fitted front and rear.
Driver technique is the big influence on fuel consumption with large cars like the VN. Reasonable drivers can expect between 13.0L/100km and 15.0L/100km around town and 9.0L/100km to 10.0L/100km on the highway.
The suspension provides a compliant ride and competent handling. Combined with the engine's strong low speed torque and a smooth automatic transmission, the Commodore has very good all round performance.
The VN is a tough and reliable car and most of the early assembly faults were rectified under warranty.
Long life and low running costs are one of the reasons the Commodore is popular with fleet operators.
There are some points to watch out for when buying a VN Commodore.
Like the Ford Falcon, they were popular as taxis so make sure you are not buying a worn out former taxi. LP gas conversions should be checked to make sure they are correctly installed and meet state regulations.
Service and spare parts costs are an area where the Commodore has its imported rivals at a disadvantage. Spare parts are comparatively cheap and there is lots of competition from alternative parts suppliers.
A well preserved VN Commodore should provide years of reliable transport with very reasonable running costs.
