An exterior vehicle body assembly comprises a vehicle body panel and an exterior vehicle trim. The vehicle body panel includes a first mounting portion having a first pivot structure and a first attachment structure spaced from the first pivot structure. The exterior vehicle trim includes a second mounting portion having a second pivot structure and a second attachment structure. The second pivot structure mates with the first pivot structure such that the exterior vehicle trim is pivotally supported about a pivot axis defined by the mating of the first and second pivot structures between an initial installation position and a final installed position. The pivot axis extends in a vehicle heightwise direction of the exterior vehicle body assembly, and the first and second attachment structures are aligned with each other with the exterior vehicle trim being in the final installed position with respect to the vehicle body panel.
