I have a ship theme. My first car was Argo (a 68 nova); The first car Jim and I bought together (an Accord) was called Dawn Treader; the Vista was named Blue Nose, and our current Vue is actually named Vingilot, but Jim has always called her green bean, and it is firmly stuck. Before the vue we had a smaller Saturn called Stella Luna.
I cannot remember ever naming a bicycle.
And our boat was not called after a car, though that thought appeals to me now. She was called Pretty Lazy. The family story goes that when my dad bought her, she was called Pretty Lady and he was too lazy to change more than one letter.
