It does turn nicely, but I believe my old W163 turned even tighter.

By official specs the W164 could turn even better than the W163 indeed.

The turning circle of a W164 is 37.9 feet. The W163 has a turning circle of 39.0 feet.

The E53 X5 (2002-2006) has a turning circle of 39.7 feet which is worse than both the W163 and W164. The E70 X5 (2007+) has an all time terrible turning circle of 42.0 feet.

Turning radius was never part of the decision making process for me. Of course, now it is. It's a whole lot easier in tight places like garages or even parallel parking.

Same here. I am used to cars with poor turning radii. As long as the turning radius is below 45 feet I'm fine. Anything under 40 is pure god-send.

Also, have I told you guys how often I drive various rented U-Haul trucks and such? I've even driven a 28-foot truck and believe that thing simply doesn't turn. I was going around turn making 3-point right turns.
