Buying A Used Car

I haven't got any experience of buying a used car in my life but my husband has. He had bought used car twice before we bought the new one. He has told me that the price of used car in Australia is too expensive, it is much more expensive than in U.S.A, and it is rip off. And driving used car is too trouble, because you have never known what problem has happened on the car before and when it will happen again. By the way the fee of fixing car is expensive to, maybe you will spend the money on fixing more than the price of the used car. So this time we prefered to buy a cheap but new one.
