I don't exactly understand that question.
With gas prices UP the way they are, used car prices are WAY UP too for anything that gets good gas mileage.
The standard "have a shop check it out before buying anything used" applies to a hybrid even more.
Now might not be a good time to do this.....unless you get lucky.
If your old one is still running good maybe you should hang on to it for a while longer while you shop carefully.
