I remember that venture well because of one car in particular- the Chevrolet Nova released as part of that venture.
I was a mechanic at a large GM dealership during that time. Under this venture with Toyota in North America GM released what was a rebadged Toyota Corolla as the Chevrolet Nova during that period. Besides the badges and nameplates this Nova had a GM AC Delco battery and a GM AC Delco radio in it. Everything else was Toyota. This car was a perfect example of the media bias against North American built vehicles at the time. Whether North American built vehicles were of lesser quality or not is certainly a valid claim, but even when there was a North American vehicle that was of on par with anything from Japan it seemed as though they were incapable of admitting it during this time period. They claimed to be providing unbiased, honest, and factual assessments of each vehicle that they reviewed for the benefit of their readers and the consumers. Their differing opinions of these two vehicles brought that claim in to question in my mind.
These cars were often coming in to the shop for one problem or the other, and there were many service bulletins issued in support of them. One good thing is that Toyota parts, service bulletins, and shop manuals could be used in a pinch. All of these things were the same as it was a Corolla. Toyota would often have service bulletins, parts for recalls, manual updates, etc., before we would receive them from GM. If we were really stuck we would go down the street to the Toyota dealer for the parts or technical information that we needed.
Despite them being the same vehicle, North American Corollas were even being made on the same assembly line as the Nova, I remember how the automobile media would sing the praises of the Toyota Corolla while at the same time criticize the Chevrolet Nova as yet another example of North American inferiority in the small car market. It seemed disingenuous at least if not outright dishonest. It was not a secret to anyone that the Nova and the Corolla were one in the same vehicle. It was impossible to believe that they did not know this as well.
