I think you guys have to decide which car makes most sense for you. But, I can tell you that we went from 2 to 1car this year, and its just not a problem, especially since one of us can always bike if necessary.

I do love having a car with good gas mileage (our new honda fit), but I also think you will be able to sell the prius for a premium right now to someone trying to get out of a very fuel ineffeceint vehicle.
