And yes Opel does make decent engines (they last and use little fuel(in combination with the Opel cars anyway)), but Opels overall quality is ass, since that GM guy is at the helm of Opel, it only took him a few years to destroy Opels image and market share....
GM has owned Adam Opel AG outright since way before WWll. Nice try on the theorizing, though.
Sure you arent thinking Holden? AS thats what the prototypes of the GTO were based on, and the production model is based on. Opel is a company that was closely related to Buick through the 60's and got pulled out of the US shortly after, they have a reputation as really really bad cars. Although some of the new ones look sharp.
Opel and Buick are "closely related" in that they are, and have been since the 1930's, both divisions of General Motors. When GM decided to import Opels in the 1960's, they chose to market them through the Buick dealer network.
Opels were not particularly bad cars, but they never caught on here. Anyone remember the Opel GT? The GM corporate link could clearly be seen in it's mini 'vette styling. The weirdest progeny were the last of the "American Opels". Did you know that GM has long owned a big hunk of Isuzu? Well . . .
After the then rising deutchmark killed any remaining chance of GM's making any headway selling imported German Opels in the US, the General shipped off the body tooling for the Kadette sedan to Japan, and had Isuzu (long primarily a truck manufacturer who kept trying to crack the car market) manufacture and import the late, totally unlamented,
Buick Isuzu Opel -- an Isuzu with a Kadette body sold briefly by Buick.
Phew.
Edit: Oh, and my late wife had a Cavalier. It was a total piece of junk. Did you know that that old cast iron 2.0L four -- the Iron Duke -- was, at it's core, essentially half of a 1955 Pontiac V-8? :Q
