What’s the worst amount of body damage/bondo you discovered after you bought the car??

Our GTS convertible wasn't too bad except for the deck lid. They had been rear ended by a motorcycle. Trunk had Bondo that was poorly applied and was loose behind the finish panel with rust behind it. Fortunately a local Mopar wrecking yard had a very nice GTS deck lid with a nicer panel that I got for $50...Hard to tell in this pic, but it's to the left of the letters.GTS Lil Cuda 1983 01.jpg
