This here is O'Malley and Christine together. I was thinking of this backstory
"Okay so the day Christine first met O'Malley years before she met The Car (1977) it was after she lost Arnie and after she put all herself together from Darnell's Junk yard. A white 1967 Chevy Malibu comes cruising to the beat as he's singing along to "Jukebox Baby" when Christine was resting. She laid her eyes on him and she felt love all over again. He was interesting and classy in his style. and he seemed to love Rock n' Roll too judging by the rhythm. O'Malley and Christine get to know each other and share a good friendship. Christine, as always seduces O'Malley in Stall 20 where she was staying. The two get busy and have a sexual friendship of just fun and company of a companionship...not that O'Malley refuses any sexual activity or anything. he loves to participate. Christine realizes she found a perfect pal to come to whenever she is confused or hurt or in need of company
