Ideas on how best to tackle this. Tried having a friendly chat and askinhg her to be more careful and apparently I'm out of order

My A4 has 4 door dinks on it, my mrs 207 has 1 and my temp Mondeo has 2.

I park away from her as I know she's a selfish fat arsed moomin, I can't stop her parking next to me though.

I'm at a loss but thoroughly fed up with having my cars damaged as she and her offspring couldn't care less
