It can be but often it’s not, particularly when people are into cars.

Things like handling, the interior quality, noise makes a big difference to some.

Would I replace my BMW with a Toyota if it handled as well, had as good engine, had a better screen and computer system and such a well calibrated gear box - of course. And Lexus IS getting close.

I don't own a BMW for the signaling. I have no one to impress and it is quite an old station-wagon, so not a head turner. My wife doesn't know shit about cars but refuses to drive the Toyota on her longer commutes, because it's not comfortable for her.

So I would prefer a Toyota that handles nice over a BMW, but it would not be a Toyota. Toyota optimizes their cars for reliability and cost whereas BMW optimizes its cars for high performance and comfort. Specifically, their cars, like other German brands, are well suited for safe high-speed cruising on the autobahn, making them incredibly solid driving machines.

yes, the masses just want signalling, that's why individual car models are not given their own model names. car manufacturers are just emphasizing their brands.

But the true enthusiasts don't care much for signalling or Brands but prefer the visual styling and the capabilities of the car.
