I have two sets of OEM Volvo roof racks made specifically for the P1 Volvo S40 (2004.5 - 2012).
One set has never been mounted while the other was used for a for a very short period of time. They've been in storage for a while so the plastic is scuffed, but they're both in near perfect condition
Both sets come with the locking key.
I have another set. No tool. Asking $150 plus shipping. Located in San Diego, CA.
