No they most definitely are not.
They're marketed as high end, but their engineering is a tour de force of cost cutting behind the scenes.
I just got rid of my 2024 BMW i4 xdrive40, for an electric awd subaru-toyota-lexus joint effort platform (there are a few variations, all related in engineering) and it's like jumping several years into the future, including efficiency, which is roughly 25% higher in the japanese (more modern) cars, the handling dynamics on the japanese platforms are far more refined, and then vastly less shitty interior materials, except the BMW seating which was good.
I've driven BMW "high end cars" for about 11 years, and emphatically recommend looking at Audi, Mercedes, and Subaru/Toyota joint efforts, as well as Tesla and Rivian, depending on what you seek.
