PROBLEM TO BE SOLVED: To provide a polymer composition suitable for production of a carbody part, providing <15 mm flection of a test piece from the horizontal plane in a heat sag test of 250°C/30 min, having high surface quality, good impact resistance and a low coefficient of linear expansion on heating combined with high rigidity, and capable of being produced inexpensively. SOLUTION: The polymer composition comprises (A) a polyamide, (B) a syndiotactic monovinyl aromatic homopolymer or copolymer, (C) a polystyrene copolymer or a polystyrene graft copolymer, and (D) an impact modifier.
