The trim is stainless. I had mine restored by a local chrome shop. They eliminated a nasty rock dent on the driver's side pillar and then polished the entire trim set. I came out beautiful. These same guys had previously re-chromed my deck trim hockey sticks, which are pot metal, and polished the stainless center section. That also came out a perfect match between the chrome finish and the polished stainless. I had put Wheel Vintique's chrome rallye wheels on the car as well and the center caps, which were stainless, had yellowed and looked odd with the bright chrome wheels. Same guys polished my caps and they look as shiny and bright as the wheels.
