That's my thinking as well. When I bought my used car I had joined a "car form" well before my purchase to not only become familiar with the car, but to wait for a member of that forum to sell one. I was and still am very happy with that purchase which was 4 years ago. Didn't get a steal of a deal, but a fair one. That's what I'd like for now as well. However, as others have said, "new" many bee worth it for peace of mind if I can find the right operating system.
As a side note, I'm now considering getting a used one for myself as well.
