Minor things like bearings, water-pump, fuel gauge.
Extremely dependable car when they are properly maintained. Very easy to fix - I have learnt how to deal with most things just by reading the service manual...
Plenty of power. The economy is better from a 5.0L V8 with a Rochester carburettor then there is with a 6 cylinder motor for sure. Less than 10 litres of petrol per 100 km in the country.
Mate, good point about the HJ, but with live rear axle and leaf spring suspension, it won't be going round corners. Neither will it be braking with the old drum brakes on the back. A much better buy is a XB Falcon, same crappy suspension and poor braking as the HJ but much more power from the 4.9L or the even bigger and better 5.8L.
There are no leaf springs on a HJ pal!
Unless you get yourself a Ute or P/van.
Much more power, perhaps from the 351 boat anchor, but not from the 302, which came with a 2 barrel carby and, from memory 210 gross HP, while the 308 was 240 HP.
