Buy OEM parts
It is simply not true that OEM parts are always more expensive than aftermarket parts. Remember that cheap parts are usually cheap for a reason, so if an OEM part is more expensive than an aftermarket part, the higher price serves to remove the reasons why the aftermarket part is cheaper.
These days, there is no telling where any given aftermarket part was made, or even who made it. The global parts market is flooded with cheap, substandard garbage that does not conform to any accepted safety and quality standards, which in practical terms, means that you could be endangering the lives of your family by refusing to pay “exorbitant” prices for safety critical parts at the dealer.
Moreover, if an OEM part fails, you know who to talk to about it, which is often not the case with aftermarket parts. The result of this is that you often have no recourse, and you simply have to buy another part at a different auto parts store, hoping it won’t fail again within a few days. Thus, by occasionally paying more for an OEM part, you can save a lot of money, time, and aggravation in the long run.
If you do choose to go with aftermarket parts, despite the risk of receiving substandard auto parts, you can often realize substantial savings by shopping around. However, when you do shop around, you must compare prices for the same brand.
If you don’t know your way around the parts jungle, it is easy to fall prey to unscrupulous dealers who do not have your best interests at heart. Reputable auto part manufacturers will always brand their products, so stick to brands you know and trust: auto parts that come in unbranded white boxes (or in plain plastic bags) may be cheap, but you just don’t know what you are buying.
“Cheap” never translates into “good quality”, which means that by the time you had replaced an aftermarket auto part of uncertain provenance for the third time, you’ve probably spent more money than you would have done had you bought the part from the dealer in the first place.
Buy used auto parts
We are not suggesting that you should always buy used parts, but where used parts do not pose a safety risk, such as trim panels, mirrors, body parts/panels, and the like, you can often save substantial amounts of money. Moreover, by shopping around and comparing prices at a few junk yards, you can often negotiate a price that will make you come back for more.
Buy refurbished parts
Major auto parts like alternators, drive shafts, and transmissions are always expensive when you buy them new, but refurnished parts can be a viable alternative that can save you substantial amounts of money. However, not all refurbished parts are rebuilt to OEM standards, so if you want to take this route, be sure to investigate the company that does the refurbishing.
Remember that no refurbished auto part ever comes with a warranty that matches the warranty of a new part, but the warranty should offer at least two thirds of what a “new” warranty offers. Nonetheless, a warranty means nothing if it is not backed up by a solid history of superior after sales service, so be sure to check out the supplier’s record with regard to after sales service.
