It's just the works carpark lol.
There is limited adjustment in the doors, but enough to make a difference. The top and bottom bolt can be adjusted with the door open, you can release the tension on the hinge by undoing the multipline bolts a bit and then lift the door up and down a few mm. It's better with 2 people, but i'm always working on my own so just put the window down and support the door over my shoulder like a gaint handbag.
There is also quite a lot of adjustment in the door catch that the door lock latches to. This is mainly in and out adjustment, but there is another cm of up and down movement there too.
