Outer Silver Door Trim B6

[Sti_Prodrive]

Ive got the crapy plastic door drim which gos across the door, Ive seen some passat b6 have a silver version of it! mines on a 06 plate

I want to know whats the best way to take them off without marking the door/back bumper & where would be the best place (price wise) to get the silver version for all round... (not talking about the window only the once that go across the door & back bumper)
