i had a '78 F150 4x4 that was "dubbed" the peach beast because it was huge and had a 70's tanish, orangish color that i have yet to see duplicated.
My '83 Zephyr that i had for a year everyone called the "Zephinator" or "the zeph" and for some odd reason everyone liked it.
My mustang is devoid of a name, but i call it "junkyard stew" becuase of it's numerous boneyard parts (as well as that when i bought it the thing should have been commited to a junkyard)
I've had several other cars, but these cars (which also happen to be my favorites) are the only ones that the names stuck.
