Car appreciation... the aesthetics, the engineering, etc

But why not the 530i? Isn't that the sweet spot of the E39, if you're not going m5?

Not that I wouldn't buy the 54i estate though, that's cool.

Because I'm a child I love the way my E63 (and the C55 before it) sound. Steering on the six cylinder E39's is meant to be better - but I'm not Senna, so I doubt that's meaningful for me.
