Does anyone else have this hole which sits between the two head rests up on the rear deck panel?

What is it for?

I have it also. I've noticed it in other coupes as well. Not sure what's it for. Sub woofer vent? Accessory ant farm? Breather hole for someone in the trunk?

i think it's for the temp gauge. i think i read something in the manual that saide it had some kinda sensor in the back.

I vote for the ant farm.

or a heated ant farm!:banana:
