Most overpriced objects on Earth: plastic hubcaps with automotive manufacturer's logo.

You can get a 10 L wastebasket made of recycled plastic for $1.44, but if it happens to be molded into the shape of a hubcap, the cost becomes $35.

EDIT: Did I say $35? I called Leith Mitsubishi in Fayetteville and they told me the cost would be around $80.
