Hey guys, My girlfriend purchased a car today from a car yard in Melbourne. The car was paid for in cash today and has a roadworthy, is registered, and was sold to her with the promise that it would not have any issues. 10 mins down the road, it dies. Turns out it's a blown head gasket and the water mixed in with the engine oil. This and numerous other small problems with the car would bring in a bill of over $3000 just to get it back on the road. I want to confront the salesman and threaten legal action under Australian Consumer Law unless the car is repaired free of cost or the money it was purchased for is returned in full. I'm just so annoyed that they would sell such an unsafe and unreliable car to her I feel sick about it Help would be massively appreciated.
