We need specifics. Engine, transmission and what exactly did not pass. A lot of things could be fixed cheaply (if we knew what they were) If you only paid a few hundred dollars for this, a thousand or so would not be bad, to "make it safe" What do you plan to use this for? RVing, camping, party bus, storage?
There are things on that Miss. list that really don't apply. Pretty sure you don't have studded tires, do ya?
If you have a problem in every catagory on the list, ya might shudda not have bought it.
Your post says you have insurance on it. I had to pull my seats and have a rep take pictures of it before they would issue insurance. (to make sure I would not be hauling passengers. Over 10 anyway)
