Should I trade my prius for a plug in?

I am not a conversion expert but I would hold pat for a while unless state incentives favor. The one thing I am waiting for is Re-Involt (the battery replacement folks) are coming up with a Lithium batt replacement for Gen2. I am curious to see what benefits that gives.

 

That was the KBB trade-in value that I was looking at. At first they said $17400 for a trade & tried to tell me that is what KBB showed. I pulled it up on my phone & showed them it said $20449 for excellent condition which mine is. It literally needs nothing but a good wash right now. There is absolutely no damage of any kind on it. They finally came up some on the trade-in but if I can't get what it's worth I'm not going to throw away money. I told him that I don't have to do this, I want to do this. Just not what they want to hear.
