In Stephen King's novel, "Christine", what kind of car was Christine?

Christine was first published in 1983 by Viking Press. The story surrounds a bright red 1958 Plymouth Fury that has something very different and very special about it since it first came off the production line. The car 's original owner endured a series of family and close friend’s deaths during the time that the car was in his ownership. After many years he decided to free himself from the Plymouth, and sold the car for $250 to a young college student named Arnie Cunningham.

Arnie is forced to store the car in a do-it-yourself mechanics shop because his family, and even his best friend, severely dislike the car. As he spends time repairing the care he becomes disconnected and cynical yet gains more self-confidence. The appearance of both the car and Arnie change dramatically overtime. Seemingly impossible repair jobs get fulfilled, though they don’t seem to be done by the pimple-faced and pale young Arnie who now seems to have a flawless completion and more adult appearance. Arnie and the car become more and more connected with each other and he names her Christine.

King has said that he got the inspiration for the story one night while driving when he saw the numbers on his car's odometer go from 9999.9 to 10,000, which led him to think of the idea of an odometer that ran backwards, thus making the car "younger" instead of older.
