I am just going to leave this reply I left here on a sibling thread as I addressed most of this there.

It is often not worth continuing to maintain a vehicle after a certain point.

I can do quite a lot of the jobs. But I don't have really anywhere to work. I live in the UK and I cannot even rent a garage within 30 miles. So I have to work in my car parking space.

Working on your car yourself, isn't hard if you have the time and space. I don't have space really.

I don't think the previous owner maintained it properly. It lived a hard life on a farm.
