Well, it's a blue/purple van. So to that extent, sure, they are similar.
But, to me the Disney front end is rounded, and looks like an Express, not a G20. The custom window is different. Disney has a horse flying through space or the sky, she has a Unicorn standing on land or in water. She has mags, Disney has steel wheels. Disney has one fender flair, she has none. Disney has a conversion van style spare tire carrier on the back, she does not. She has side pipes, Disney does not. Disney side markers, door handles and mirrors are non-de script.
If they did this film like they did Cars, they spent a lot of time in the field researching. That may have included some photos of her van, but I would be willing to bet it included photos of many others as well.
The Route 66 people and places that inspired the people and places in the Cars movie trade on the notoriety, and enjoy having been the inspiration for places and characters fabricated for the movie. See
"Cars on the Route" on Route 66 in Galena, KS.
Cars on the RouteI hope this van owner can't do the same. She has a tremendous opportunity to be an ambassador for the hobby, meeting and greeting kids at shows, showing them an "Onward"-like van, maybe hand out custom trading cards of her van...kids will want their photo in the van, or next to it. They will remember it for years to come. Or she can be bitter about it and not engage...I'd recommend the former.
