I listed a Toyota Caldina a year ago. Had rust issues and wrecker had offered $350. I put on Trade Me (and disclosed the significant rust and warrant issues) for buy now $500 and another wrecker bid $500 (why he didn't choose buy now is beyond me).
Woke up on morning after it closed expecting to deliver to the wrecker for $500, only to see it had sold for $1,600 after a last minute bidding war!!! A recent immigrant with English as second language with no idea of value and had bid way over the odds for it! Conscience got the better of me, I could't rip him off, so told him $600 would do it.
No doubt it ended up at the Ellerslie Car Fair for $2000 where it was being sold as his daughter's as she had upgraded.
Props to him if he was such an enterprising entrepreneur (-;
