These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Author's Saving Throw: The first third of the novel is in the first person. At that point, our narrator gets sidelined — and apparently Stephen King didn't realize this was going to be a problem until he finished the chapter. So, the next third is in the third-person...
Cargo Ship: Definitely. Not merely shipping, this is one of the few canonical pairings of this nature and with both being sentient, as Christine and Arnie openly love each other to the point of mutual obsession.
Nausea Fuel: The bullies couldn't just be satisifed by beating the hell out of Christine; they had to crap on the dashboard.
Stealth Pun: Christine doesn't actually belong to LeBay for most of the books, but the words his unending fury can also be read as his unending Fury. Which she is.
Tear Jerker: Christine mourning Arnie's death by playing their "song" (movie).
This turns into a Jump Scare when Leigh thought Christine died. Christine was really just having a moment of silence before resuming her rampage.
Visual Effects of Awesome: The shots of Christine's regenerations were actually shot using mock ups that were built with more flexible materials that looked like metal which were sucked in by pumps with the film being played back in reverse to complete the effect (which was surprisingly effective).
