Some call that chromeshadow trim. Comes standard on E92 335s from PML. Costs $1400 to buy that from PML as parts, close to $2000 for parts + installation. If you prefer the chrome trims, lots of PI 335s are willing to swap. My advice to you - get it as stock.gstone said:the 335i that pml brings in comes with black trim around the windows, presumably that is the high gloss black satin? Personally, I prefer the chrome trim. any comments on that?
