Aye the VauxPels had a 'soft car' rep' at the time and any hard driving usually ended in a trip to the scrapper for a rear axle, or gearbag, or engine! The clutches in them were still coarse splined as I recall and small diameter.
When I worked in a garage about 1990 the number of even the later 1980's FWD Asconas, Cavaliers or Kadettes with a warped head! About two a week! That OHC family engine was pure dung but a lot easier on the juce than a Sierra or Cortina so people bought them.
The 1970's Vauxhalls though, the did have a good strong body and manys a teen' buddy had a Chevy with a pinto engine and 'box fitted, with the gear stick so far back it knocked the handbrake!
I remember those wee Bedford HA ex-GPO or telecoms vans, about guaranteed the diff would or was wrung!
Yeh the Viva was a comfortable slow car but you could as you say easily drop something more potent into them - well not so much in the Viva rather the Kadette/Chevette. There was an old guy around here with a 1973 Kadette coupé, the fastback shaped 2-door in bronze. When he died there was a scramble amongst the Opel rally guys to get it!
Yes indeed, as is said NZ is a kind of eden for 1970's cars. I can only guess your climate keeps the rot at bay. I suppose while the Avengers, Escorts, Vivas and so-on that were built in NZ being a smaller production run mean't the workers didn't get as bored as the armies of workers in the British factories did. Then too I suppose the steel was pressed in the UK and shipped to NZ so they would have had to treat the panels for shipment and better undersealing by the NZ plants mean't a far better body in the long-run.
Some people oiled their cars from new, hey it was not hard to do nor was it expensive. My Avenger has signs of waxoil applied a long time ago but not everywhere. Next spell of hot weather I seriously intend to remedy that!
