As for glove box interior finish, you should take a look at the cheesy glove boxes that GM cars come with. Compare them to the better ones from Europe, where often times, the glove box is chilled or refrigerated, has nice felt covered shelving, and actually has illumination.
GM can do a lot of things to improve its cars.
It's amusing when the stories of the Old GM leak out. There was the story that Opel/GM Europe believed they made better cars than the NA divisions, and believed that their cars should be taken on as GM's global vehicles, not the NA divisions. There was a lot of in-fighting regarding that. Ultimately, GM Europe does have the better detailed and put together car because of the smarter details and the technology that is/seems more current. And the platforms are better equipped (ie Euro Epsilon vs NA Epsilon).
To simply say "It's ok to have halogen lights and plastic glove boxes" is displaying a case of tunnel vision.
