Are you only looking for used trim pieces...or will new work as well. They don't appear to cost too much...here's a link to the online parts database where you can get the part number to order new. You can't order from this site yet...but you can look up the part numbers and then order from your local BMW dealer. I searched generically choosing a 1993 525ix Touring (1/1993 mfg date)...you can start over by clicking the link (in green type) that says
"Select Another Car" and enter you car's VIN and then you can search specifically for you car. You can also see see the "main catagory" and "sub group" to find the tail gate parts index by looking along the top at the green type where it says
Vehicle Trim and
Trunk Trim Panel:
