Funny anecdote time: my first car was a used Honda Civic. The owner was selling it much below KBB price, because it had a problem: the rear doors would not open from inside. I take it home, and was going over the car with some friends, and one of them finds a switch on a rear passenger door: hmm, what does this do? He flips the switch, and we try to open the door from inside, and voila! The door opens. Flipped the other switch too, and the doors were functioning fine. I think I saved 20% of the cost of the car simply because the owner didn't know about child-proof switches. :D
