1. The History
When buying anything that’s used you rarely know the history of the product. The same holds true for auto parts, unfortunately. Consider that when you purchase auto parts from a junk yard you rarely know if that part has been through an auto accident and is a good enough piece to put on your car. Even though most of the auto parts that can be obtained through a junk or salvage yard are purchased at your own risk and without a warranty, there are some major risks associated with doing so.
2. Too Unreliable
As mentioned, used auto parts can also be purchased from auto repair shops. The reality at most auto repair shops is that the used auto parts that are there are usually kept in one large pile in the back of the repair shop. If you buy a used alternator from the repair shop then how would you know if it’ll last? It is very possible that the auto parts that are purchased from a repair shop are no good, or else if they are halfway decent auto parts they may just break down the next week. The auto parts that can be obtained through an auto repair shop or a salvage yard are just too unreliable to justify buying. Of course, you may very well be offered a refund or exchange if this were to happen, but the best thing would be to stay away from used auto parts altogether.
3. Getting Ripped Off
Another possibility, and perhaps the greatest one, is the fact that you are always able to be ripped off when buying used auto parts. Even if you don’t buy the used auto parts through a repair shop or a junk yard, if you do buy used auto parts through a private dealer then you always run the risk of getting downright ripped off. What is even more discomforting is the fact that you may never even be able to get a hold of the person ever again, too.
In the end, it really doesn’t matter whether or not the part really does work or not. The fact of the matter is that buying used auto parts is just downright risky and dangerous. Even though millions of people engage in this practice daily, used auto parts should be discouraged!
