Volvo still design, develop, prototype and even mass produce cars in Sweden just like they always did. They haven't had Swedish majority ownership this century but still do their thing.

That could change of course, but so far so good for the Swedish economy and fans of Scandi design.

Since Chinese tech is clearly state of the art for EV's I think Volvo could be in a good spot if they get to continue as they have so far. Win-win.

As for realiability, 500 000 km is no problem for a decent EV and Geely makes good ones. I wouldn't worry about that aspect either way.
