Car dealers dumping cars for weeks

For over 6 months a car dealer has been repeatedly leaving several cars on a very small parking space.

I live in the flats on the corner of alexander street and George Street. There is extremely limited parking for the houses and flat residents in that area, including on alexander street itself. It has been made worse by a car dealer repeatedly leaving cars there for weeks on end, often badly parked too caused issues in general to work.

I live in the block of flats on the 3rd floor (no lift) with 2 children, my youngest is 1 YO. Due to no lifts I have to carry her up and down several times a day which is very painful due to back issues and tennis elbow. Parking further away causes significant issues and increased pain. Prior to the dealer leaving cars there we could all normally park on the street, but this issue and their inconsiderate way of parking not only takes up limited and valuable spaces but the poor parking takes up more space than needed. The car dealer has ignored residents reaching out to stop this.

Is there a solution? Even if this means parking permits. The block of flats is owned by paradigm and we have no allocated parking like over blocks on the road do. There are several elderly residents who struggle to walk far and several of us with young children.
