What is the best jalopworthy eco vehicle? I expect at least one person to answer vw tdi wagon, and one person to answer miata... But what other vehicles out there are worth mentioning? Bonus points for being "greener" then a prius.

Personally, I want to save an old CRX, spend wayyyy too much money on it and end up swapping in a modern 2.0 Honda engine, kept to stock power/couple fuel economy friendly mods like intake/exhaust. And make the rest Singer level of attention to detail
