I think I found the perfect car for me: The TH!NK Ox

On their webpage, the creator promises that this car will provide open source interfaces but does not yet reveal what can be controlled by them.

TH!NK, a company based in norway, has announced to build this car in 2011. In times where humanity has to relize that fossil fuel will not last forever it would be nice to call such a car yours.

Let's see what happens in 2011 On my part I'll put some money aside in case my current car breaks somewhere around the time the TH!NK Ox becomes avialable to the public.
