Judging from that, for an MOT you cannot have any sharp edges and the doors must open/close. Both the doors and hinges look mullered there, is it even worth the hassle?
What's the condition of the B pillar like? Its going to need 2x new doors, new outer sill welded in, new rear quarter plus lots of spraying ... is it worth it on a car worth maybe £500?
No offence, just might be worth pursuing a new car and continuing to break this one. With that level of damage, I wouldn't feel too confident driving it
But ultimately, if you're happy with the rear quarter damage and you can get a cheap pair of doors and just drive it with a damaged outer sill and probably keep on running - but its resale value will be almost nil.
