Post 2006s starts to have Chrome part in the middle vent.

Good catch, I swapped the 2006 + center A/C vents into my 2004 for the chrome bit. I think the instrument bezel also has this shinier finish. Want to get my hands on the OEM trim ring accessories but also don't want to pay 70 bucks for two tiny pieces of aluminum...

They have some Iron in their coating as they attracted to the magnet.
I also notice the instrument bezel and A/C controllers. waiting to get hands-on a pair cheap.
The side vents might be the same with Mazda 6 or others.

Finally, I manage to pick the whole face of post-2006 for free, as part of another deal!
Only need to change the bezel, all interchangeable, I keep the whole face as spare if a bottom gets scratch.
