This is the piece for the front passenger door as an example. Should give you an idea of what the whole thing would cost. If you only have a couple sections falling apart, this might be the way to go. This is the 'bright' or fake chrome trim. There'* also black available, but different part number of course. Different part numbers for each door.
If you decide to go this way, give me the location of each piece you want to replace, and I'll get you numbers and prices.
