Polyurethane, the wonder-polymer used in everything from appliances and textiles to electronics and footwear, is apparently the car building material-of-choice for this "sculptor" in Lithuania. You'd recognize his particular mixture of the foam as the same type of messy stuff we use to fill cracks and gaps around windows. Tossing all OSHA and DOT regulations out the window (no problem in Lithuania), this crafty coach-builder mixes up batches of PU foam in 2-liter soda bottles before "applying" them to the framework of his creation. Held in place by scrap cardboard until it sets hard, the foam can then be sculpted, sanded, primed, and eventually painted.
Our best guess is that the rolling "donor" chassis was once part of the Mercedes-Benz family. Do yourself a favor and check out the huge photo gallery, and take particular note of the 30-inch rear wheels (not nearly as gaudy as the jacket this guy is wearing) and the upholstery treatment on the inside A-pillar. Regardless of what the designer was thinking, with that much self-expanding foam inside the cabin, airbags are most likely unnecessary. And, wind leaks are probably non-existent. Flammability, however, might be a problem.
