door panels

I'm looking for information on replacement door panels for the 328, my step daughters car is missing the rear panels and the fronts are falling apart. Well ..they have become unglued. Does anyone know of a source of replacement panels. Aftermarket is what I'm looking for or factory if they are reasonable. Thanks

Any BMW dealership parts depart will be able to order you replacement parts. And you get a discount if you're a BMWCCA member, which would probably be worth it.
