Our long-term 2009 Audi S5 has an aluminum outer mirror shell.
Well, at least it looks amazingly like aluminum.
I gave it a rap with my knuckle the other day, then verified (once again) with the Audi Guy: the mirror shell is plastic. But you really can't tell by looking at it, even up close.
However, I think that mirror shell would look even better in body color. What do you think?
Let's vote!!

Red looks better than the fake aluminum. The fake aluminum looks like something you would see on a souped up mid-90s Honda.

Nah, you'd see fake carbon fibre on a "souped up mid-90s Honda".
My vote goes to the I-can't-believe-it's-not-aluminum mirror.

While it's disappointing that it is not real aluminum (which it should be for the price... maybe that glory is saved for the even more expensive RS models?), I like the contrast it provides. Sure, it may not be a perfect match with the S5's red, but I really like it contrasted with Sprint Blue or Meteor Gray.
It would be really nice to see options for the cover, particularly when matched with lighter colors... but please, no carbon fiber :P

I'm a fan of the aluminum-look mirrors. They're a subtle touch to distinguish the S-models from the standard models.

Should be an option. I like body color with the red, but I would like the aluminum look with meteor gray or black.

Setting off the mirrors like that gives the car big ears. I don't like it at all. I want those mirrors as integrated as possible.

Mirrors? Who needs them?
And now my friend, the first-a rule of Italian driving.

The Audi S5 is all about class. I like the classy aluminum. Just my opinion

The A5 and A4 have body color mirrors. The S5 and S4 have the aluminum look precisely to be something different, even if subtle. (Like the extra tailpipes.)

Aluminum-like mirrors = gingerbread.

I like the aluminum-look mirrors, it's a unique touch. Every other car on earth has body-color mirrors.
