Are All Car Parts the Same?

Restoring a classic car using Original Equipment Manufacturer (OEM) parts versus aftermarket parts is a decision that depends on various factors, including your goals, budget, and the specific project. When it comes to restoring classic cars, owners are often particular about how they choose to go about it. Restoring classic cars is often done out of the owner’s desire to return the car to its true, original, and authentic form so are all car parts the same?

The hardcore car enthusiasts have a vision in their minds of what the perfect version of a classic car looks like, and it usually involves only original parts. However, there are plenty of people who simply want to get their classic cars up to functional, drivable quality so they can show them off on the road and at car shows.

Each option has its advantages and disadvantages:

Using OEM Car Parts

OEM parts are made by the vehicle’s manufacturer. These match the parts that came with your vehicle when it rolled off the assembly line.

Quality and Fitment: OEM parts are designed and manufactured by the same company that produced the original components for the vehicle. As a result, they often have superior quality and fitment compared to aftermarket parts.

Historical Accuracy: If you’re aiming for a concours-level restoration or want to maintain the historical accuracy of the vehicle, OEM parts are typically the preferred choice. They ensure the car remains as close as possible to its original factory condition.

Resale Value: Restoring a classic car with OEM parts can enhance its resale value among collectors and enthusiasts who value authenticity and originality.

Warranty: Some OEM parts come with warranties that provide peace of mind regarding their quality and performance.

Drawbacks of Using OEM Parts

Cost: OEM parts are often more expensive than aftermarket alternatives. Restoring a car with OEM parts can significantly increase the overall project cost.

Availability: For older or less common classic cars, finding OEM parts can be challenging, as some parts may have been discontinued.

Using Aftermarket Car Parts

An aftermarket part is any part for a vehicle that is not sourced from the car’s maker. Several companies make parts designed to function the same, or in some cases even better than the original.

Cost: Aftermarket parts are generally more affordable than OEM parts. This can be especially advantageous when working with a limited budget.

Availability: Aftermarket parts are often more readily available, even for older or less common classic cars, as many aftermarket manufacturers produce a wide range of components.

Variety and Customization: Aftermarket parts may offer a wider variety of options, allowing you to customize your restoration with different styles, materials, or performance enhancements.

Drawbacks of Using Aftermarket Parts

Quality and Fitment: While aftermarket parts have improved in quality over the years, there can still be variations in fitment and quality compared to OEM parts. It is essential to choose reputable aftermarket manufacturers.

Historical Accuracy: If historical accuracy is a priority for your restoration, some aftermarket parts may not replicate the original components faithfully.

Overwhelming selection: If you are not familiar with aftermarket brands, the selection could be overwhelming, and there is some chance you may get a bad quality part. Even a part as simple as a spark plug can be made by dozens of different companies and comes in numerous variations.

Resale Value: Some collectors and enthusiasts may prefer cars restored with OEM parts for their historical accuracy and authenticity. Using aftermarket parts can potentially impact the resale value in certain circles.

Is There a Risk of Counterfeit Parts?

Today, sadly, there is always that risk. Think about how there are knock-off watches, sunglasses, and handbags. Auto parts, unfortunately, fall into a similar situation. Airbags, brake pads, wheels, electrical components, and various other engine and drivetrain components are among the parts most commonly at risk. Counterfeit auto parts are still on the market, despite government and industry efforts worldwide to quell the activity.

How To Spot Fake Auto Parts?

Keep an eye out for poor quality, misspellings, and wrong colors. When shopping online, look for listings that include several high-quality photos and detailed descriptions that include exact specifications. Always read through customer reviews if there are any.

One way to avoid counterfeit parts is by purchasing from reputable companies and sellers, preferably those with a dedicated customer service team available to you before and after the sale.

New or Used Car Parts

When it comes to finding a way to fix your classic car, there are several options you can consider. You can purchase brand-new parts, or you can search for used car parts at salvage yards at a discount.

Choosing Classic Car Parts Comes Down to Personal Preference

If you are looking to complete a classic car restoration, there are a couple of ways you can go about it. When it comes to choosing parts for a classic car, you can either opt for OEM or aftermarket parts. OEM parts are original and authentic, made only for that specific car. Aftermarket parts are more versatile and as a result, much more customizable.

Finally

All aftermarket parts are not created equal — but all OEM parts are. This creates its own set of advantages and disadvantages. If you are familiar with several brands or work on your own car, aftermarket parts can save you a lot of money.

In summary, the choice between OEM and aftermarket parts for a car restoration depends on your goals, budget, and the specific project. For concours restorations aiming for historical accuracy and maximum resale value, OEM parts are often preferred. However, if cost savings or customization options are more critical, aftermarket parts can be a viable choice, if you select high-quality components from reputable manufacturers. Ultimately, it is essential to research and weigh the pros and cons based on your unique restoration objectives.
