LOL, he is no where near 85% done more like 30%. You need to see before pictures. Was cowl replaced? Does not look like it was taken all the way apart to do, suspension off etc. Would not be a show car unless you back up and do some over. Were quarters replaced, butt welds or lap welds? What was original engine 6, 302 351?
I bought a failed restore farther along than this with extra fenders, ram air and back to rolling chassis with all NOS Ford components. Q code vert with built engine and transmission and rear for $5,500. I am doing some of his panel repair over because of lap welds and taking back apart to do a better job. I have seen fully painted projects that failed or owner passed on for less. Yes the body work and paint is very expensive today, $50.00 an hour and up. You can put over $5,000 just in paint and body materials pretty quick also.
Heck I might die tonight and there will be 15 cars for sale next week happens everyday.
He cannot expect to get what he has in it back. The one I bought had $16,000 in receipts and was not 50% complete. They are a black hole for money for sure.
