This entire top case project from Sierra BMW has been a complete disaster. I spent over $1,6000.00 on ths OEM BMW top case. I have invested entire days trying to get this silly lock mechanism (that was included) to fit and work properly into the top case.
Unsuccessful. A complete waste of 2 days of productivity. How hard can it be for Sierra BMW to ship out a tip case with a lock that works. Also, no brake/tail light included.
So frustrating to work with SIerra BMW.
