Favorite "stealth" everyday luxury item?

[john dough]

Nothing stealthy and small, except for my platinum wedding band. It looks like silver when it has not been polished in a while. When we picked them up in 1999, we paid $500 and $280 for our bands; currently, the rings are $2000 and $900.

In my car, I have a Pioneer Premier deck, amp and speakers, and if I take off the faceplate to store in the glovebox, you can see none of it when I park.
