To start off the story, last November I hit a deer. The body shop was kind enough to let me hold onto the damaged bumper, so I took the liberty of fixing it up
This is what I started with:

While installing the temporary bumper, I level the 9500ci antenna.
The antenna is has nothing metallic blocking it's view past 180º
We'll see how mind blowing the performance increase is to decide if I want the grills in or out. I don't think the difference will be much and I like the more stealth look.
