The part that seems too good to be true is the price. I don't know where that came from. I did some google searching and came across a page that casts some skepticism on that low of a price point. Now, that page claims it'll cost more like $26,000. If so, no thanks.. I'd be interested if it were $600 actually.
This is a really neat little car anyways. One website says it's actually two seats, the other one is right behind the front seat... like a jet fighter. The motor is a 299cc single-cylinder diesel engine. I'm not a mechanical person, is single-cylinder even possible? I'm sure it doesn't have the acceleration of a jet fighter :) But with gas prices probably never dropping again, unless we have another deep recession, anything that uses less gas is awesome in my book.
Begin tangent here....
Electric cars are available now, but only really economical if you build one. It's very much like the early days of the Ham Radio pioneers or the computer hobbyists of the 70's. If you want one, it's better and cheaper to build than it is to buy.
Here's a link to a blog of an Aussie ham who has posted about his EV (Electric Vehicle).
According to him, the electric car uses pennies per km of electricity. Their electricity prices cost more there than they do here, that's for sure. I believe they also have a solar panel array set up, although I don't know the capacity, that actually supplies all the energy the car needs.
I'm just going to copy & paste a chart from a .doc file on this page

Mr. Rowe is a pretty good salesman for EVs, I have to say. :)
