Bought a used car ($10k) from a guy off gumtree. I asked him if it had car finance on it. Seller said it was paid off. Later it was found out money was still owing on it (around $4000). I failed to do a PPSR check. Do I have any legal ground to sue him if he is uncooperative in giving me a refund? I'm not sure where I stand. Most websites say I have no guarantee to title if I didn't do PPSR but this link http://www.consumerlaw.gov.au/conte...loads/industry_guides/motor_vehicle_sales.pdf says I do as he did not disclose the security at time of purchase.
