Why tho? It’s not like they’re really good cars, the build quality is sub-par, as you note the brand has really suffered, the home-grown tech would be difficult to integrate, and the automation a liability.

The supercharger network seems like the major asset someone might be interested in.

And secondary would be a pretty strong software team as historic manufacturers have had a hard time taking that turn, but at the same time that would likely clash with the existing teams and practices so the benefit is not a sure thing.
