When i got my first Mystique, i thought they were pretty cool.
Over the years, i've cared less and less for them; they feel kinda grandpa-ish now .
I've actually thought about painting mine gloss black a few times.

But hell, for $20, i would buy them then mold a screen into the radio/HVAC trim piece, then relocate other stuff....I've wanted to experiment with something like this for a while. $20 really isn't too bad of a deal if they fit, i say go for it; you can always paint them later.
