and in Petone New Zealand. Holdens were marketed as Chevrolet's, and the "Ranger" was the Opel Rekord B produced in Port Elizabeth. The Constantia and Kommando models. GM divested in 1982 from pressure in it's US plants, etc. of Apartheid when Nelson Mandella was sent to prison.
When the 1963 EJ Premier came out, it's intitial domestic content was 92%. The Holden Lang Lang proving ground was also new then.
The first V8 Holden used was the Chevrolet 307. Opel used the 327 in the Diplomat.
It was available from 1968 in the HG and HK series Kingswood, Premier and Brougham models.
Following the Holden HQ through HZ models which are my favorites, very similar in design to the then GM rear drive X bodies (Nova, etc), they moved to a more Opel Rekord "D"/Senator design. The HQ-HZ had a front sub frame, and all coil spring suspension with long travel front control arms. The Statesman and DeVille models had a split grille similar to a 1972 Pontiac Lemans. Wheelbase was 112" for the Monaro coupe and Kingswood sedan. Wagons and Statesman was 114".
Mazda installed a twin rotary engine in the large Holden sedan, calling it Roadpacer for the Japanese market.
Holdens best sales year was 1973, @ 200,888 units. John D Rock from Oldsmobile took over as Holden chairman during the change to the Opel Commodore/Rekord/Senator change in 1981. The final Statesman DeVille and Caprice HZ models were in 1982. The J body fwd Camira was plagued with quality problems.
Australia had a button badging plan enstated by the Govt. which saw shared cars between Holden, and Toyota in the 1980's.
The final Holden V8's were imported from St. Catherines Ontario. The last Pontiac GTO, and the G8 were Holdens. The Vectra was an identical to the Opel car, as is the Insignia, The Cruze is identical to the north American model.
China builds the Buick Park Ave. which is a lengthened Holden Commodore/Staesman/Caprice. Daewoo in Korea now builds the North American Cruze and Malibu for Holden and Australia.
South Africa used Chevrolet the Lumina name for the last Monaro, and Caprice for the Statesman.
