So you can't afford a full-sized Batman Tumbler from The Dark Knight. But maybe you can afford a go kart sized one! That's something, right?
Well, it's not for sale, but the plans for it are. Yes, you can build your own sad little Tumblr for $30 and an existing go kart. Then you can drive up to Christopher Nolan's house and pitch yourself as Robin in the next movie. I don't see how you can go wrong! [eBay via Jalopnik]
