What should I name her?

Drive it. The car will suggest it's own name. Trust it to tell. It's like voodoo. My ION just named itself Onion after 7 years of not having a real name.

And the Valiant has been called Mothra for so long I have forgotten the origin of it. But I've never called it anything else in over 30 years.

You'll hit the right name. Just. Be open to hearing it.

Howzatt for some New Age nonsense ? But it's usually how it happens.
