Despite the relatively flimsy appearance of their roof structures, late-model convertibles are no riskier than non-convertibles, according to the analysis of crash and fatality rates. In fact, both crash rates and driver death rates were lower for convertibles than for non-convertible versions of the same cars.

Convertibles are generally more expensive because it's not just a sedan or coupe with the roof left off. A properly engineered convertible needs extra re-enforcement of the frame to increase the structural rigidity lost without the pillars and hard roof that sedans have.
