I bought an E90 320i which has black door handles. These detract from an otherwise good-looking car. I discovered that it is possible to purchase chrome covers for these handles from a firm called Chromiumtech vie E-Bay U K. I purchased these and fitted them for a total cost of $120.
If you want to know what they look like installed on the car, the Chromiumtech website has a screen-size picture displayed.
I hope this is of interest. Incidentally, Chromiumtech also sell handle covers for E46 BMW's.
