After his parents refuse to let him keep the car at the house he is forced to store it at a Do-It-Yourself garage run by Will Darnell and later the airport. Later he restores the car to its natural beauty but the more time he spends with Christine the more she takes over his mind. Now obsessed with the car, his personality changes and he no longer wears his glasses as if his vision has improved greatly and he becomes humourless and arrogant but also assertive and cruel. After Leigh Cabot becomes his girlfriend Arnie gets into a fight with Buddy Repperton which results in Repperton being suspended. Later on when Buddy and his posse co-trash Christine, Arnie is shocked to discover all the hard work he put into restoring the car has been ruined and is determined to restore her back to normality. Later on he strains his back and starts wearing a Back Brace and later on Dennis and Arnie have an argument in which he goes against his own friends and in the process is killed in a motorway accident.
