Have a smashed (front end) e60 that i purchased for the box and a few electrical items which i have all removed and ready to scrap the car away but thought id hold onto the doors incase i need them in the future

Ive had a look and cant figure out how to remove them - they dont seem to be able to removed using spanner and lift of the hinge like an e46
Did see that the door was also bolted onto the hinge with e-torx nut but i cant open the the door wide enough to fit one there with a rachet attached

Is there a special tool or any ideas how to remove the doors?

Thanks

 

would something low profile like this work? basically converting a crescent wrench into a socket.
