Old drawings: Cars

Next in my line of old drawings is a non-palaeo one.  I always liked drawing cars but was never good at it.  So I'd doodle and try to practice from time to time.  Here, I've got a selection of cars; a Subaru Impreza, some Japanese pick-up truck, a sedan, and another Japanese-style truck with a kind of near-future Sci-Fi anime feel.  Incidentally, Smarty Pants is a product idea I had as a joke (though the technology isn't available to make it happen).
