Hey gang - just bought a car - Nissan GTiR hatchback from carsales. The guy dropped it to my work today (test drove yesterday) and I paid him. Met with my wife - drove 2 km before heat gauge shot up... 10 minutes later went down and then steam came out so I turned it off straight away and left it at my bros house. Do I have a legal leg to stand on? I rang the guy and said I was broken down and he sounded really sorry but said there is nothing he can do. Is over heating a big problem for a car ie expensive or is it just a matter of getting new radiator, pump, flushing etc? Any help or advice would be great thanks!
