Heavier than unibody, causing lower performance and/or higher fuel consumption.
Far less resistant to torsional flexing (flexing of the whole car in corners), compromising handling and road grip.
Lack of a crumple zone causes higher rate of death and serious injury (in some cars, but larger cars such as the Ford Crown Victoria are highly rated for safety). Some cars have adopted a "front clip" and "rear clip" format similar to what is used in NASCAR where the car is split into three sections, and the clips absorb the impact, allowing the "clip" to be replaced when repairing the car.
