I would dearly love to go hybrid or totally electric, but the commercially available cars I'm seeing seem like a lot of cost for only a little benefit.

I recall a "Mother Earth News" story about a guy who build a hybrid out of an Opel GT for $1500 and got 75 mpg. Has anyone else here ever gone the DIY route? To what effect?

I have a Chevy S10 that I was hoping to convert to hybrid electric when the conventional engine gives up the ghost. Can anyone recommend plans, etc.?
