I was actually looking at some of the exact same vehicles a while ago (the Velar wasn’t out and the x4 was the older style) and ended up getting into an X6 instead. In my view, it’s hard to justify spending ~$1000 on a new x4 m40i when you can lease an x6 now for at least $300 less per month, especially since almost everyone who sees an x4 (m40i or otherwise) will instantly assume the driver just can’t afford an x6. Not that popular perception should or does matter to you, but let’s face it, all of these coupe-like SAV/crossovers are about making a statement, not practicality.
Also my impressions of the Macan and X4 were they kind of seemed like the “worst of both worlds” to me - too small and cramped to provide the extra space or utility of having a higher clearance vehicle, but too big and tall to drive as well as a 718 or 4 series. While the X6 itself is pretty impractical, the boot space and rear seats are still big enough to be comfortable which at least offers some justification for getting a giant, tall coupe.
Good luck!
