Used or New?

I stopped by the local Toyota dealer last week.  While talking to the salesman (and it is almost always a man), I asked a question that I've been wondering about for some time.  I've been looking at used Toyota Matrixes, but the prices on the used ones seem to be almost the same as the new ones.  WHY? 

Of course, the salesman had an answer.  The warranty on the used, certified cars is actually longer (100,000 miles) than the new ones!  (60,000 miles).  Go figure.

I don't really care, though.  I still want the used car to cost less.
