I've heard it is kind of hard to find X5's with it too. I got lucky when I found mine - it has it. I really wasn't too familiar with it until I got mine, then people told me that know about them and they said they don't see it that often. Sometimes when I park, I just hit it to lower it for the look............I kind of like it.
