Here's a few of those names, and stories behind them, from friends in the Festiva community!
Ben in Kentucky:
It was my brother who named Frito. Shortly after acquiring the vehicle he was cleaning it out for me and found an empty bag of the Frito’s snacks in the interior. His brain connected that to the film “Idiocracy” in which one of the main characters names is Frito, and also features a white Festiva GL in a rather hilarious monster truck segment. I liked the name, particularly for its unique brevity, and for its similarity to the another white Festiva in the community called “Pedro”.
