Uh, guys, I think your geometry lessons have failed you: added load will not effect that rear gap. However, SNOW will. Just think about it; it's there for a reason.
And, #5, your lens is NOT centered on the hub, therefore being forward a few inches, optically, it makes it even worse.
Cheers,

people would you just believe the fact that it is normal and done on purpose on all the cars so there is a space for the car to lower when your shocks absorb the potential trunk weight load !!! the weight has to distrubute somewhere so the cars balance and driving abilities remain safe...... it is not lilke the gap is rock solid no matter what weight and how many people in the car....

..... have somody sit to your trunk and watch the gap and you will see !!!
OK Pete we got your point don't need to post twice

Alright then time to go check mine when I get home (yes I am on the forum during office hour )

Thanks for the feedback and the checking

I would have also thought that additional weight in the trunk would further reduce the gap around the top of the wheel, but would have only slight impact on gaps A and B.

In any case the reduction of gaps A and B (although slight) should be proportional to eachother.
I.e. the ratio of gap A:B (lets approximate it is equal to 1:2) should not change.

IT IS PERFECTLY NORMAL !!!

it is geometry and physics here REAR GAP B: the gap is here on purpose. it is there so you can load your trunk with WEIGHT. If you load your trunk or have full car of passengers the car will obvisuly go down and that is where GAP B will get smaller as the car body will go down towards the wheels and ground.

If you load your trunk it is not like that the whole car moves towards the ground evenly in the overall car lenght.... it will be mostly the back/trunk that will lower.... that is why this B gap is there

..... have somody sit to your trunk and watch the gap and you will see !!!
Makes sense to me, think its the same here:
