If you aren't familiar with the term "sleeper" as applied to a car, you may find this a little out of this world.

A sleeper looks like just any other car you see on the street. If you just bought a new Camaro, perhaps even a Porsche, you may want to race and put down other cars to impress the woman with the thought that you can't lose. When you lose, you just ran up against a sleeper.

Some say beauty is only skin deep. In the case of the sleeper, all the beauty is hidden under the skin.
