Long term tech costs of our escalades.

Interesting story here..

But I'm not worried about parts costs due to damage.

This is my first escalade so what worries me is the costs of magnetic shocks, power running boards, cue system, and ac controls due to its integration in the cue system.


Has anyone ever had to replace a whole cue system?

Thanks.
