Earlier quoted context omitted.
The proper analogy is that your Alienware breaks, and Alienware replaces your RTX3080 with a 3080Ti. When you resell it, you can and should identify it as an Alienware with a 3080Ti.
Upon closer analysis, all analogies will break down. I'd argue the car in the sumtotal of all the parts in it. So rather your analogy about Alienware is: You own a dell gaming pc. Under warranty repair, Dell replaces some of the parts with parts from an Alienware build. Are you allowed to put on Alienware decals on your Dell desktop and re-sell it as an Alienware?
It seems like you're agreeing with me and creating a less appropriate analogy at the same time.
