^Door handle on prefacelift is silver and it's darker/titanium color in my 4.8iS.
I used 3M Scotchprint Brush Aluminum vinyl to wrap interior trims for a local E39 owner. He has Silver exterior and the wrap match that pretty good. It has a little texture in there, instead of just blain smooth vinyl.

In the car

I also used it to wrap the picece on the shift knob of my 4.8iS. That piece is painted some how and look pretty bad.
Before with the paint

After with the wrap and in the car. It match 95% to the silver trim I have.



I would use that if the door handle in your X is silver. If it's darker, I would use Brushed Titanium. Material was bought from metrorestyling.com
I hope this help somewhat with your choice.
