If you shop, you can pick up a used Prius for between $12,000 and $16,000. That's basically the same cost as most of the newer but used guzzlers. I'm just wondering why there are used Prius's and Civic Hybrids and Insights available?? I would think that people would have snapped them up if things were that painful. Assuming 17MPG, $3.07 per gallon gas and a $300 a month note, a typical used guzzler would cost you well over $3800 per year to own and operate. A used hybrid would cost about $1100 a year to own and operate.

Even a junior high kid can understand this math!!

Interesting idea, but I was looking at CalCars.org :

Q:What cars can be converted?
A: At the moment, only 2004-2006 Priuses. Older "Classic" Priuses lack the low-speed electric-only mode and the battery storage space that makes this possible. Honda Insight, Civic and Accord use an entirely different design: the electric motor never runs without the gasoline engine running at the same time. Other hybrids, including Ford Escape, Toyota Highlander and Lexus 400H, are possible future candidates.

I'd have a hard time believing that many other people would care, but it might dissuade me.
