Fix her up yourself or take it to the local high school that have vocational classes and let them try to do some of the body work. Buy all the parts yourself. I bet you could buy the car back, fix up everything and still have some money left over. The only drawback would be that the car's title would be salvage. This happened to me also while I was in high school and I had a 123. If you love this car so much THEN GET IT FIXED. I would.
You can buy mine
