PPE+PS is not used very often in automotive applications. When it is used, it is normally found in fuse boxes, circuit box covers, cowl vent grilles, a few bumper covers from a famous German car company that starts with "B" and ends with "W", and other underhood plastic where heat resistance and chemical resistance are required. It is some times used outside of the engine compartment, too. For example, it is sometimes used to make hucaps, TV housings, a famous gaming console that starts with "P" from a famous company that starts with "S" and ends with "Y" parts, hardhats, and many other applications where a rigid, durable plastic is required. PPE+PS is a rigid plastic with a relatively high melting point.
