One thing that has only briefly been touched on is that this choice is not just about aesthetics over practicality, but also driving dynamics. A Grande Punto 3dr for example has a torsional chassis rigidity of 19,700 Nm/degree compared to only 16,500 Nm/degree for the 5-door. This equates to superior suspension geometry intergrity in the 3-door, so it should be the better drive.
