Premium Sound w/ DSP

[Bimmer4life]

Premium high-fidelity 12 speaker sound system with Digital Sound Processing (DSP) and 2 Subwooders.

I've been looking in the past few weeks for a pre-owned 4.4 04' or 05' X5, either private sale or dealer pre-owned and have yet to find one with the Premium Sound w/ DSP.

Has anyone ever bought a pre-owned X5 that just happened to be equipped with the Prem Sound?

I'm making matters worse cause I want either Titanium Silver or Sterling Gray with black leather.

But good things are worth waiting for, I don't like to settle for something I won't be happy with so waiting 6 months till I find the exact one is not a problem for me. But am I dreaming or will the exact combo finally appear for me?
