obviously he feels like you have not told him everything about the car and found that the car had way more problems than the ones you told him about.
you painted the car and tried fixing/bondo the frame … I find it very hard to believe you didnt know about the holes in the floor.
stop hiding behind the forum rules … the mods should close up the loophole and ban you from selling stuff period.
BSKZ … take off the sideskirts and see if there any metal left under there.
