I did this in Thames Ditton BMW dealership when picking up my alternator in the summer. Luckily, I left the sunroof open so I climbed up the car and in through the roof. The guys walking up to drive the 530 parked next to me with the sales guy had a great look on there face as I popped out the boot with the alarm going and calmly said to them, "Don't mind me, just testing it to see if I can get a full size male body in the boot!" and then proceeded to the parts desk! hahaha....
