Haven't named my sewing machine or my latest vehicle. However I named my dress dummy "Headless Gertrude"
My first car was "The Gerbil" (Subaru Justy with 3 cylinder engine)
**running joke was that my friends would give me a hamster/gerbil so I could put in another cylinder
My second car was O'Reilly, as in Radar O'Reilly because it would sense a police car in the immediate vicinity, and you could not make it go faster until the police car left.
