Cm model not consistent with their metal base, I want to order one but like this model its just a plastic base. So far as I know mclaren senna gtr has metal base.
Some model has plastic base like ER34, 35GT-RR, evo IX, evo X, 765LT and many others. Because for the early model they made casting for plastic material so for the future release it will be has plastic base. Same with inno64 R34 Z-Tune always has plastic base even though it's new release. But for new model, it usually has metal chassis.
