' In our composite models, we pair a die-cast interior with a newly developed injection Acrylonitrile butadiene styrene (ABS), a thermoplastic polymer with special blend of different materials for reinforcement of the body....' Why diecast interior? To give it some weight so it doesn't feel like a plastic model kit?

IIRC, Fujimi and Tamiya used ABS in some of their 1/24 car models, specifically suspension components, for strength.
