Deciphering a cars history. I hate 'owner two'.

Yep, we hope we are kicking ours forward with the right approach, took lots to get there and never through.
I just can't understand on how someone would shove bondo in like that, and sell it. I only paid $1500.00 for the car ten years ago, knowing the dr. rail and torsion support were shot.. but if I were the guy that bought it and paying good money for it, and later found that bondo, it wouldn't even be 'hey, I want my money back'... it'd be a good ***-kicking time.
