Depends on the laws in your area, for the most part as long as the car is current with Insurance, registration and inspection then there really isnt a whole lot that can be done.
I did get rid of an asshole neighbor's car once the inspection stickers expired and told the cops that small kids were playing in the car each day and I didnt want them to get hurt. 2 hours later the cops were out and the car was being flatbedded away.
I did have to deal with an outraged neighbor when the cops told him who called. He was mighty pissed and went out of his way to be a dick to me and my wife, but, also moved a month later
If you can get handicapped parking assigned to your place then no one can park there without the proper ID on the car.
Or, you can buy a few old beaters from a 2nd hand lot and park in front of his place and play the same game he is back at him. a few rusted Nova's outfront should make him get the message.
