I just spoke with Bob Ciasulli Toyota in Little Falls, NJ. They told me that I could order a Prius now, and that in 6 - 8 months I would get the car (with the specs I desired). They also said that I could get either a 2004 or 2005 model at that time.

I did this over the phone, and sometimes sales people will tell you anything to get you to come in -- so, I'm not sure exactly how accurate the info is.
