Same here. I was looking for the Polestar 4 very, very much, as a replacement for my 2016 V60 Cross Country. Maybe I could finally live with having no rear window (which I find stupid), and probably I could get around the fact that it is built in China. But the real deal breaker is its size. I don't want a car that is larger (and most of all, wider than my current car. A bit longer would be okay if that means more trunk space. But the Polestar 4 seems to be a lot longer than my V60 while having a significantly smaller trunk. There's just no benefit of the added length. And I'm really using my trunk space for my sports gear, can't go smaller!
If you ask me, the whole idea of the Polestar 4 is wrong for European customers. Polestar obviously put a lot of emphasis on rear seat space, as this is a big thing in China (where almost every sedan is sold in a longer version with more rear seat space). Next they moved the roof strength structure to the back to give rear seat passengers more headroom, which is kind of okay. But they could also have moved it behind the front seats, same solution as the Tesla Model 3 has. That would have meant a glass roof split in two halves, but who cares? A full-length glass roof is only a thing for rear seat passengers, so again, that's why Polestar went this way. As they went this way, the rear window became so tiny that they decided to remove it, and also the trunk became unpractical because that strength structure is in the way. This car is just totally the opposite of what I was looking for.
