A model vehicle in a first scale including a first body portion constructed of a polymer material, an undercarriage portion having a top surface and a bottom surface, the undercarriage portion and the body portion being secured to each other and defining an inner cavity therebetween, a plurality of wheels rotatably attached to the model vehicle, and a first amount of ballast disposed in the inner cavity of the model vehicle. The weight of the first amount of ballast is at least equal to the difference in weight between the weight of the first body portion and the weight of a second body portion constructed of a metal in the first scale, the first and second body portions having substantially similar outer dimensions. |
