1 24 Ferrari Racing Kit 488 Challenge 2017Diecast model kit for a 2017 Ferrari 488 Challenge in 1: 24 scale. Assembling the diecast and plastic components is easy straight out of the box, mostly by snapping them together by hand or by screwing them in place using the included screwdriver. The level of detail on the finished model is astounding, with a faithfully reproduced chassis, opening doors that reveal the interior, and a rear hatch that lifts to expose the engine.
