Similar to Paul, if I had sold this airplane to someone and found out it was in such bad shape, I would at least give them part of their money back. Obw said he flew it about 30 hours, so 30 X (say) $80/hour dry = $2400. Take that off the refund, then go visit the shop where the airplane is to satisfy yourself it is really that bad. If true, give obw back the rest of his money. I don't do owner assisted annuals because I am not able to spend much time at the A&P's shop. I rely on my mechanic to let me know what needs to be done. I often run out there then to take a look with him, then approve the fix. If our airplane looked like that inside the hidden places, unless he told me I likely would not know. I had a prepurchase done a few years ago. The mechanic (by the way, it was $600) called me and said something like "you don't want to buy that airplane." It had corrosion issues. He said he could probably push a screwdriver through the stabilator. I sent the owner the squawk list and he said he had been flying it and the mechanic was wrong. He sent the deposit back to me, though, and we each went on our way. A lot of folks here say they would be afraid to ferry the airplane somewhere, but obw was flying it (probably) regularly before his mechanic started the annual. Sometimes it is nice to be fat, dumb and happy!
