my daughters named my rigs with a little disney influence. the mj is named herbie cause it's white with stripes. the other rigs have names like horace, jasper and oddball. my '45 willys got tagged with grandpa. i never have or ever thought about naming a rig but after yrs of saying white, blue, green, junk, *%$#, etc... i call them by there names all the time.
edit: but mommy's car is "mommy's car" ?????
