If you have 2 trolley jacks you could always move the car and put it on the zig zag lines, the coppers will not only fine them £90 but will also issue 3 points to the owner too.
About 20 years back one of the neighbours blocked my fathers car in our garage, so I called 3 of my mates and we bumped the car out of the way, unfortunately during moving it we managed to kink one of his wheelarches, he was not best pleased but as it was on private property there was nowt he could do about it, he never parked there again and he moved house some 9 months later.
We had issues with the next residents tho, they decided that they could park at the rear of their house (where they have no legal access for vehicles as its was land owned by my parents!), anyhoo after me and my bro went round to explain this he soon came round to our way of thinking.
All was well for about 3 weeks until he decided to try again, no chance matey!, me and my brother went round again and had words, he got a bit shirty so we thought fair enuff you been warned, it was then we decided to move my parents caravan to behind his house placing it exactly 3ft from his back wall which stopped ANYONE parking there and it also blocked out most of the light from the rear of his house. We left it there for 4 months until we moved it and my father installed foldable poles there to stop anyone parking and every time they came back from holiday that caravan was back up against his house!.
After this my parents got sick of it and got a solicitor to record that those 3 houses do not have vehicular access to behind the house, it was added to the deeds of those 3 houses so everyone knew the score!.
The lageal bills were split with the neighbour who was also sick of them trying to park on his land (we shared a Driveway to access the 2 houses behind!.
No more problems after that!.
