I'm sorry to hear. Can't stand it when you lose a perfectly fine vehicle to accidents - and don't get much because its "old". Its happened to me too.

Well, first find out how much they are going to give you. Then I would post some pics.

Like you said, there are alot of variables and it just depends.

Are you a handy mechanic? Do you do bodywork? Do you have another vehicle to use while doing possible repairs? Do you have a heated garage? Do you have any mechanic/body & paint connectiions?

140K is certainly high-mileage. I doubt they're going to give you much. If they total it, whatever they give you you have to use most of it to purchase the X back - which probably doesn't leave you much for repairs.

Also, I can't remember but I think the title changes to a salvage title or something if its totaled by the insurance company.

Not sure how that would work out if you want less money for repairs.

Parting it out is always a pain as it takes time to sell piece by piece.

Just some thoughts.
