A roof box – Thule Motion 200 – 410 liters, size 172×82×45.

Condition is good, with minor scratches, but almost unnoticeable :)
Very convenient quick-mount fasteners – can be installed even by one person, though of course easier with two.
Opens from both sides, comes with two keys.

Optionally, I can also sell a BMW Wingbar Edge roof rack.
