Neighbor refuses to respect my property line (parking area) after a surveyor laid out the points. Touches my car on sitting within my property lines.

Neighbor (husband and wife) feels where my car is parked is their area even after the survey was shared. They fold the side view mirror on my car and park inches from car at time if they can will try and park a tire over the marked boundary set by surveyor. I have them told them not to touch my vehicle but they countiue to touch it. HOA washed their hands of the issue said they do not handle these matters but sent them a letter urging to respect each other's boundaries. They claim m there is nothing in the bylaws to enforce parking. It's endless harassment I feel, to date I take pictures constantly and have some video footage of how they park their car next to miner blocked my car when parked. The wife is the aggressor the husband urges me to talk to her but I am leery of that. It could be viewed as I(the male) am going off on a female and wouldn't look right in the eyes of the police I feel. What's my next approach?
