I wonder if the Chinese made GM cars are better made than the GM cars made in N. America?
If GM/China has no UAW labor on its assembly lines, then the quality is probably pretty good. The horror stories of American union "workers" is well known. Refer to Lordstown, Ohio for one such case where union "workers" would stop in the middle of a welding job when the shift ended.
Union "workers" == shoddy goods.
