You want something really weird, in the late 70’s Buick sold something they called the Opel Isuzu. In a tortured piece of cross-marketing, Buick took cars built by Isuzu and then marketed through Opel and sold them with all three names still attached.
Our 77 Bu - er - Op - umm - Isuzu was actually a fun little car to rive, but the interior was as cheap as cheap could be, and the manual transmission made an odd sounding little chirp whenever you let out the clutch. GM finally had to issue a service bulletin that said, in effect, “Yes, they ALL do it.”
The Saturn Astra is the Opel Astra. It’s not based off the platform, it’s literally the same car off the same line in Belgium with Saturn badging. It’s a cool little car.
I’m surprised the UAW hasn’t raised hell about GM importing cars from foreign assembly plants and bypassing their own workers. Isn’t this one of the reasons why GM or Ford didn’t import other cars in the past? IIRC this was the reason why GM would only import a limited number of rebadged Holdens as GTO’s from Australia.
GM, Ford, and Chrysler have been importing cars for ages and ages. And not just low volume oddities like Merkur, but high volume stuff like the Avalanche and Tahoe. Trainloads of imported American cars vome in from Canada (which is still foreign) and Mexico every day.
(For the record, even those plants maintain thousands of US jobs; the only operational difference is the in-plant employees.)
