Nope, you're not the only one who names their cars.
I'm driving Sally Saturn. Used to have Fenella Ford, kept that station wagon from 1974 to 2002. Sure miss her, she was a real work horse. Sally is too small to carry much building materials.
DH used to have Samuel Scout, an International Scout. Sammy took us all over the mountains. He could dig in and climb over the steepest roads ever.
