Essentially, the '59 is demolished and the Malibu, while messed up, has an intact driver's compartment.
Of course, even after the wreck, the '59 Bel Air is still a better looking car than the pre-crash Malibu, but that's more an indictment of modern vehicle styling. Too bad they had to destroy a sweet old ride to prove a point.
