What do you mean "if" he dropped the price and you didn't know? It was advertised for $20,500 when he updated it on 9th Feb (link)... and we all know Carsales require a seller to log on every 3 weeks to keep the ad active. So, why would he have to keep the ad active on 12th March (link posted by that tonton dude) if you had already bought it before 9th Feb for much more money? You're not making much sense.
