I sold a car having made full and honest representation of its condition (excellent) within the advertisement on the internet. The person who purchased it did not take it for a test drive nor request a vehicle inspection, but chose to test certain aspects within the basement of my apartment block, stating that he knew what he was looking for. A previous potential buyer paid for an NRMA inspection and the inspector told me it was in excellent condition, as, did the mechanic who performed 100k service a week before it was sold. The buyer 6 days later rang to say the clutch had gone, insinuating that I knew it had a problem which I vehemently deny. He has subsequently demanded $500 towards costs of replacement and advised he has "the means to pursue this in other manners, however, would prefer to settle this issue with you quickly", a statement I find quite threatening. I understand that a buyer of a private car has full responsibility to check the car over as it is considered to be a "buyer aware" situation, as advised by the Office of Fair Trading, who do not consider it to be a consumer issue. My concern is that he may go to the small claims court. Would he have any recourse on myself through this means?
