Gently accelerate from a standstill and listen for any clunking or hesitation in the transmission, as these 5-speed automatics can show signs of wear in the valve body over time.
Cycle through all climate control settings, including the heater and AC, as the blend door actuators are known to grow tired and may require a bit of patience to sort out.
Operate the power convertible roof (if applicable) through its full cycle to ensure it moves smoothly without stalling, as hydraulic rams can develop minor weeping issues as they age.
While driving at low speeds over bumps, listen for any suspension knocks or rattles, particularly from the front lower control arms, as the rubber bushings have likely seen quite a few years of NZ roads.
Usually the time to inspect the cooling system, including the radiator and hoses, to ensure the V8 runs at its optimal temperature.
A common point where the engine mounts may become compressed, often noticed by a slight increase in vibration while idling.
Consider having the alternator and starter motor checked for performance, as these electrical components have had a long service life.
Keep a close eye on the engine oil level between services, as these M113 engines appreciate being kept topped up with quality synthetic oil.
Ensure the transmission fluid has been changed at some stage in its life, as it keeps the shifts smooth and the gearbox happy.
Regularly clean the drain holes around the sunroof and scuttle panel to keep moisture away from the interior electronics.
Treat the leather upholstery with a quality conditioner to keep it supple and protected against the strong NZ UV rays.
Make sure the spark plugs, all 16 of them, have been replaced according to the service manual to maintain that signature V8 smoothness.
