Opening a new auto repair shop is an exciting venture if fixing cars is what you love to do, but there will be some things you’ll have to plan for.

One, you’ll need some really good mechanics to help you do the work.

Two, you’ll need a building and the right tools and equipment.

Three, you’ll need access to auto parts.

Just about every repair you make will require replacing auto parts, and you’ll have to decide between OEM vs aftermarket parts.

Both are good but they are also very different.

If you’re not sure which type you should buy, you might be able to make this decision after comparing the pros and cons with both types.

OEM Parts

OEM stands for “original equipment manufacturer.” An OEM part is the type of part you find in a brand-new car. When a car is manufactured, they put the car together with all OEM parts. Every part in the car is OEM.

When a car develops a problem and needs a part replaced, you can often replace it with an OEM part. This means that you are buying the exact same part the car already has.

It is made by the manufacturer and will look identical to the part you take out of the car when putting in the new one. When auto dealers fix cars, they generally only use OEM parts for the repairs needed.

Here are the pros and cons with buying and using OEM parts for car repairs:

The Pros

OEM parts offer a huge benefit which is that they offer an exact fit. These parts come straight from the company that manufactured the original part.

If you’re replacing an alternator in a certain car, the OEM alternator you get will be identical to the one you remove. You won’t have to worry whether it will fit or not, and you won’t have to wonder if it will work or not because it will.

When you order an OEM part, you also have the benefit of not having to make a choice. There will not be dozens of different ones to choose from. You have just one choice. This means there is less confusion when ordering parts you need.

Finally, OEM parts generally come with a manufacturer warranty. The time frame of the warranty may vary but you can usually be certain that it will have one.

The Cons

The first downside to using OEM parts for car repairs is the costs. OEM parts are almost always going to be more expensive than aftermarket parts.

Secondly, OEM parts can sometimes be harder to get. You can usually get them by purchasing them through an auto dealership, but there are times when parts become hard to find.

For example, if you’re looking for an OEM part for a car that is 30 years old, the manufacturer may no longer make these parts or have any in stock.

One last thing to note about OEM parts is that they may not work as well as an aftermarket part. If the OEM part had some type of flaw that the manufacturer never addressed, it will still have this flaw when you buy it today.

If an aftermarket parts manufacturer discovered the flaw and fixed it, the aftermarket part might actually be better than the OEM part.

Aftermarket Parts

The alternative to OEM parts is aftermarket parts.

Aftermarket parts are not produced by the manufacturers that build cars. They are built by companies that manufacture auto parts.

This means that aftermarket parts are not identical to the parts your car was built with when it went through the assembly line, but the parts are designed and made to be just about identical to the OEM parts.

When you buy them, they are brand-new just like OEM parts. They just are not exactly the same. Most auto repair shops use aftermarket parts for their repairs as they offer a lot of benefits when compared to OEM parts.

Here are the pros and cons of buying and using aftermarket parts for car repairs:

The Pros

Taking a look at the pros of aftermarket parts always includes the benefit of the cost difference. You can often save up to 40% on these parts vs OEM parts.

Two, as explained above, aftermarket parts often work better than the original parts due to the auto parts manufacturer addressing and fixing the flaws the original part had.

Finally, aftermarket parts are so easy to get. You can buy them just about anywhere. You can easily order them online or pick them up from any local auto parts store.

The Cons

The first downside to understand about aftermarket parts is that, while they can often be better than OEM parts, there are also times they can be a lot worse.

Some brands just aren’t as good as others so it’s important to choose a good, well-known manufacturer when buying these parts.

Aftermarket parts do not typically offer a warranty but there are times they do. This is something you’d have to ask about when you purchase them.

The other thing to know is that it can be confusing when ordering them as there are often lots of different options you could choose from.

If you plan on using a courier service for your parts, you should know that you can purchase both types of parts.
