Lower Window Sill Trim - This is the complicated part. Word from the wise... If you are trying to do a trim swap with a 330 owner (taking their chrome trim), you can not reuse this trim. In the process of taking this trim off, it will bend (it is made of metal). When you straighten it out, it will have small bubbles in it, and it wont look good. It will look like someone took a ballpine (sp) hammer and had a few swings at your trim. If you are going to chrome trim, you will have to buy these parts in some way or form. When I did my trim swap with James from bimmerworld, we did not know this, and James was curteous enough to buy me the trim. The black trim from the 325 can be reusable if it is taken off properly. Its made of plastic.
