Can I just reinforce what other users have said about the LED headlamps, they are absolutely superb! I've driven the F25 with dynamic Bi-Xenons for a couple of years (so I'm pretty used to their characteristics & capabilities) and all I can say is that the F15's LED'S are on a different planet. If anyone is trying to decide or justify choosing this option, think no more, just tick the box and move on
MC seats are another such option, adjustable in every direction - if you can't get comfortable on these seats then you must be deformed
Just tick the box!
I like driving the X5 in sport mode though have configured that particular mode to modify the Chassis only. That way I get the improved steering weight and feel along with the increased damping rates without the gearbox hanging on to gears any longer than normal - suits me anyhow!
