Thanks to my brother, the brilliant fellow who thinks about things like what cars my characters drive, I have a winner, a very close match to the crazy car in my head that scared everyone near and far. It's name is Chevelle, with alterations, of course, but here she is!
Can you see it? Hear it rumbling? What did he say; "Saturn's car made a sound like a legion horde of demon horses screaming, hooves pounding on shattering glass as the motor revved." I'm totally putting it into the prequel. This is what it looks like in the novella, "Wilds", which will come out this winter sometime. Hope hope. Anyway, Thanks you genius brother you!
