Buying used cars has its own advantages and disadvantages. Probably the best advantage that you could ever get from it is the fact that it is less expensive than buying a brand new car. It also is slow in depreciation since they were indeed pre-owned. Next is the fact that you get lower tax to pay on it and you are able to get lower deals in insurance costs because unlike with the brand new cars, most of the time, the parts that you have on your car are already at low cost. It would also be more convenient that the reliability data would already be available from Consumer Reports. The disadvantage would be if you were not able to get something good, it would mean higher maintenance cost, especially if you have no idea on the accident and mechanical history, which can of course be checked, provided you get the vehicle identification number.
