Corrected entry: When Christine is on the assembly line and in later shots in the movie she has a white top but when Arnie sees the car in George's yard it has a red top.
Corrected entry: Christine is a 1957 Plymouth Fury, and is shown being assembled on the assembly line in 1957. She is painted 'Autumn Red', as per Detective Junkin's remarks later in the film. However, the 1957 Fury was only available in one color: 'Buckskin Beige'. In fact, all of the other Furys shown on the assembly line are the correct color. The producers apparently made Christine red to give it a more flashy, sinister look than what the beige color would provide.
Corrected entry: Christine's headlights are visible through Buddy Repperton's rear window as she is chasing him. Repperton makes a pretty quick steering maneuver to get away from Christine, and her headlights are shown moving sideways in the rear window to simulate this. Unfortunately, the movement of Christine's headlights is far too slow to correspond to the quick movement of Repperton's steering wheel. It was done in a studio and looks pretty phony. (01:14:55)
Corrected entry: At the beginning of the final scene when our hero says "They really cleaned this place out," they must not have noticed the little white car that Christine runs into on her first suicide run. (01:33:50)
Corrected entry: Christine's "hard" exhaust note was dubbed over from a much later car, probably a Chrysler Hemi with at least a 10:1 compression ratio. Late fifties cars had much lower compression ratios, around 8.5:1, due to the lower octane fuel then used. They obviously wanted her to sound more menacing.
Corrected entry: Christine's production line is shown stopping at 5pm exactly. Car production lines are very capital-intensive - in 2011, they cost about £10,000 an hour to run - so they are usually run on two or three shifts, finishing at 6am, 2pm, or 10pm. Meal breaks are usually half way through the shift, so that doesn't fit either. In any case, until the 1980's, there was usually some allowance for "washing up time" at the end of each shift - the men (in those days) would finish at ten to the hour to have time to wash their hands and change their clothes.
Corrected entry: In filming the movie, both 1957 and 1958 Plymouth Furys were used: they had similar body styles, but quad headlights were not allowed until the '58 model year. The '57's had what looked like headlights inboard beside the real headlight, but were in reality only chrome ornaments. In some scenes, the car starts as a '58 then changes to a '57, then back to a '58.
Corrected entry: The restored Christine has yellow and black late '50s standard California license plates with the number CQB 241. The only time the letter Q was used at that time was on special plates for ham radio operators, and even then it was a different style; the type of Q they used on Christine wasn't introduced until the late '60s.
Corrected entry: In the library, when Dennis is dared to ask Leigh out, he walks past her and removes a book from a shelf. The book is 'Christine' by Stephen King. (00:32:20)
Corrected entry: While on the assembly line in the beginning, Christine's air filters were brass colored. After Arnie buys her and she restores herself, they're chrome. Doubtful he found them in Darnell's junk heap.
Corrected entry: In 1958, Plymouths could be ordered with radios (as was Christine in the movie). However, radio technology at that time still used vacuum tubes and vacuum tubes take time to warm up. Transistor (solid state) radios require no warm up time and produce audio instantly when turned on, but transistor radios were not used in cars until the early 60's. Typically, vacuum tube radios takes approximately 5-10 seconds for audio to be heard after the radio is turned on. In the assembly line scene (as well as later scenes), the radio is turned on and music is heard instantly but this is simply not possible with a vacuum tube radio.
