Schlepcar was a composite vehicle using parts from a dune buggy and a Volkswagen. In its natural state, it is a rundown green ruin of a vehicle that was discovered in a junk yard by three youths. Upon hearing the sound of a particular cavalry trumpet horn, Schlepcar could transform into a highly functional, sleeker representation of itself. In Wonderbug form, it had a shiny metallic red frame, blinking headlights that resembled eyes, and a twin-bumper system that resembled white lips on a mouth. It could also fly and talk.
