Boxy-sedan-70s

Upright three-box silhouette with slab sides, thick chrome bumpers, flat vertical grille and square headlights, vinyl roof, two-tone lower body over roof with a pinstripe, named animatable groups: four spinning wheels only (pivot at each axle center); doors.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
