Some nice options I come across every now and then as I am sure some of you too.
Would be nice to post pictures with description.

BMW E60, HIFI amplifier, rare option in Ireland.



BMW E60 power socket in the trunk, along the plastic trim



BMW E60 foldable rear seats (Love this one)



BMW F10, night vision camera



BMW F10 Park Assist, the car parks itself up between 2 cars.



BMW F10, convenience closing (?), just touch the handle and the car locks itself up, as long as the key is not inside, but with you.
