Some of the obvious plastic trim should actually be metal, but it's hard to fault the quality of the materials that Acura uses inside the RDX. The perforated leather looks and feels terrific, the headliner is woven mesh fabric, the dashboard is soft touch (hard plastic up top where people rarely touch), the steering wheel feels good in the driver's hands, and the matte-black plastics have a coarse texture that keeps them from looking and feeling slippery and cheap.
