For my money, Peter Wherrett did the best car reviews and reports on general motoring on ABC Torque.
This video (so old that it was recorded in black and white film) is a classic Wherrett dissection of some serious engineering problems with the then new Holden HQ.

Wherrett was not the only motoring journalist of the time who was critical of poor vehicle safety. But he was able to use TV as a medium to clearly demonstrate this to the public. The short section on roll understeer is brilliant, so too is the section on how to fix locking rear brakes with a load proportion valve.
Absolutely awesome how much great footage that the ABC was able to squeeze out of those very heavy 16mm film cameras of the era. Using film also meant doing as few takes as possible.
Sure, Top Gear and Fifth Gear are great entertainment. ABC Torque from the 1970's is pure motoring journalism.
