To be fair he is definitely a bellend.
But you are doing a good impression of one aswell:
-contacting the police for good measure = bellend
-moaning about his amount of cars/where they park =jealous bellend
-being interested in what he's having built in his back garden =nosey (Garry get involved) bellend
-calling his family 'clan', because there's a lot of them =bellend
-turning your nose up because his boy earns money washing cars( would you rather he earned it breaking into yours?)= stuck up bellend

I dodn't contact the police for good measure, I contacted the police because the threatened me and my family. He did it for good measure.

I wasn't complaining about the number of cars but about the fact that they caused an obstruction and were used to vex and bully people.

"Clan" is a perfectly normal word for a family in Scotland.

I had a problem with his son because he was causing an obstruction and giving it large to people trying to get past him.

What's your problem? Do you also think you've got the right to intimidate your neighbors? Or could you simply not be bothered to read my post properly?

Quibbling anout the meaning of an individual word in a long post as though the meaning of the whole thing turned on it = bellend.
