Minor bump - some advice needed please

[londonman]

LOML was straightening up in the Waitrose car park and as she inched back out of the space so she could straighten up a bit, a woman was driving by very close to the line of parked cars and so LOML had a slight bump. Looking at the damage done to the womans' car and that done to ours and her initial comments when my wife got out to talk to her, we smell a rat and think that she may well be being a bit opportunistic about this. So I went round to her house to take some photos and measurements.

Don't get me wrong...if we did the damage then we'll get it sorted. Just that to my eyes, the damage does not seem consistent with what happened. Would welcome your thoughts, guys.

This is the womans' car. My wife was reversing back squarely.

and our car (the scuff mark on one of the images is an old impact by me with a stone wall...oops)

The height of the bump strip on her car is 20" above the ground.

The height of the bump strip underneath the number plate on the Mazda is 17" and the height of the bodywork above the number plate is 25" so I can't see what on our car would produce the damage on her car.

To my untutored eyes, hers is old damage, the bodywork is still dirty - I would have expected some of it to be rubbed off as she was moving at the time. The indentation on the bump strip looks as if it had a point impact from the corner of a car reversing into it. But I am no expert and so really welcome any comments.

Many thanks
