Welcome to the all new Holden Heaven
This site was first established in 1999
HZ 1977
The final H car in the series that started with the HQ and it was another refinement of the preceeding model with it's major improvement being RTS (Radial Tuned Suspension). In fact the the RTS Statesman was acclaimed as being the best handling large car available in Australia. All models also came standard with four wheel disc brakes, (although you could option drums on the rear but why you would want to is beyond me), and this improved the HZ so much it scared the other manufacturers to work on there own handling packages.  The later HZ was really a great handling car and the Ute was in a class of its own, it not only had comfort but it handled brilliantly on sealed roads and even better on the tracks dirt roads.  The HZ was produced right through to1980.

Statesman

The new Holden Statesman was rated the best handling large car available in Australia with it's four wheel disc brakes, RTS suspension and 5.0 V8 it had a package that was packed with luxury. It was such a great package that the opposition was a little worried and they had to re think there vehicles.  It came with a plush interior with extra thick seats and sound proofing to add to the drivers and passengers comfort.  Even though it was a big car for Australian standards it used its size well to give a feeling of gliding over bumps yet was able to handle the corners when pushed hard, it was a treat to drive.  I owned a Statesman and the only thing I changed on it was the air filter which I bought an after market unit. It was larger and less restrictive than the stock unit which gave slightly improved power and economy with it being able to suck air from all directions unlike the very narrow passage on the stock item. There is however one slight drawback, I was able to hear the 5.0 V8 engine a bit more under hard acceleration but then I actually liked that mild noise.
