I recently bought a car from a private seller in Sydney. The car was registered only one month before I bought it, which reassured me that the car was in good condition. Prior to purchasing the car, I asked the seller if it had ever been in any kind of accident, to which he replied no (I have this is writing). One week after purchasing the car, it broke down. The mechanic then found that the car had been in a very serious accident, which required almost all the motor parts to be replaced (with second hand parts). The mechanic won't even allow the car back on the road until he has done the repairs. The mechanic who gave the seller the initial pink slip should not have dreamed the car roadworthy as it is not. I now have repair costs of almost $2000 and would like to know what my options are, considering the seller lied about the state of the car? Thank you.
