Good Car Names/Nickname?

iv been trying to think of a good name for my car and the ones iv come up with are somewhat what i want but not exactly... "Studder" (sometimes i have to jiggle the key to start it) and "Jinx" (the other day i was out with a friend when we saw someone on the side of the road with a flat tire, we laughed and a little while later my car's tire just popped) anyways i was wondering what some of you have named your cars, or if you could give me some creative ones. some other characteristics of my car are, its gets good gas millage, its a four door, and its a pontiac... oh and i like to think of my car as being a female
