update, I do not like the idea of widening the car, but possibly lengthening it instead. While the trunk may not be usable with the skis, boards or bikes on the rack, taking them off you would still be able to use the trunk, especially if you made a rack with a hinge to allow the part connected to the trunk to fold up separately from the trunk, allowing you to then open your trunk. The hinge would then be able to lock back down in place and allow you to put your skis back on when you are done accessing your trunk. All of this probably does not make sense and I will need to try and make models... Sorry guys.. (again, just thinking out loud and trying to think outside of the box)
