Athena
I've never named my vehicles - like never never.
My gal thought I was crazy and kept trying to get me to name them.
So... my '99 Runner is "Athena" because I mistakenly that she was the goddess of the hunt (it's actually Diana). It stuck, so she's Athena.
My old Pathfinder was Igor because it was a beast. Xterra was Thor, I have no idea why, she named it. My Civic is Scarlet because she's red.
