Porsche 928 Used Parts: A Practical Guide for Owners and Enthusiasts

If you own a Porsche 928, you know that keeping it on the road can be a challenge. Parts availability for this iconic front-engine V8 grand tourer is not what it used to be, and new OEM components often come with eye-watering prices. That is why many owners turn to used parts. Buying used can save you a lot of money, but it requires know-how. This guide covers the best sources for Porsche 928 used parts, what to watch out for, and how to make smart purchases.

Why Used Parts Make Sense for the Porsche 928

The Porsche 928 was produced from 1977 to 1995, and many parts are now discontinued or only available through specialty suppliers. Used parts are often the only way to find certain trim pieces, engine components, or interior parts. Even when new parts are available, used ones can cost a fraction of the price. For example, a used starter motor might run $50–$100, while a new one could be $300 or more. The same goes for alternators, brake calipers, and even body panels. Used parts also let you source genuine Porsche components that fit perfectly, whereas aftermarket parts may require modification.

Where to Find Porsche 928 Used Parts

Finding reliable used parts for the 928 requires knowing where to look. Here are the most effective sources.

Specialty Porsche Recyclers

Several businesses specialize in dismantling Porsche 928s and selling the parts. These recyclers often have a large inventory and can ship nationwide. They also typically offer a warranty (30 to 90 days) on parts, which gives you peace of mind. Look for recyclers that list their inventory online and have good reviews from the 928 community.

Online Forums and Classifieds

The Porsche 928 community is active on forums like Rennlist, Pelican Parts, and 928 Owners Club. Owners often sell parts directly, sometimes at very low prices. You can also post a “wanted” ad. Because sellers are enthusiasts, they usually describe the condition honestly. Always ask for detailed photos and ask about mileage and condition before buying.

Local Junkyards and Pick-and-Pull Lots

While rare, junkyards in areas with high Porsche density (California, Florida, Texas) sometimes have 928s. Calling ahead saves time. If you find a car, you can pull the parts yourself, which is the cheapest option. Bring basic tools and a flashlight. Be prepared to remove parts carefully to avoid damage.

Social Media Groups

Facebook groups like “Porsche 928 Parts for Sale” or “Porsche 928 Owners” are active. Sellers post parts with prices, and you can negotiate directly. Payment via PayPal Goods and Services offers some buyer protection. Always confirm shipping costs before paying.

What to Check Before Buying Used Parts

Not all used parts are worth buying. Here is what to inspect to avoid getting a dud.

Visual Inspection

Look for cracks, rust, excessive wear, or signs of repair. For electrical components, check that connectors are not corroded. For interior parts, examine the grain and color under good light. Faded or mismatched dye can be corrected, but it adds cost.

Mechanical Function (When Possible)

If buying a part like a starter or alternator, ask for a test video. Some sellers can bench-test the part. For brake calipers, check that pistons move freely. For engines or transmissions, it is risky to buy without a compression test or history.

Part Numbers

Porsche uses specific part numbers for different years and options. Cross-check the part number on the part (or seller’s photo) with your car’s needs. Websites like PET (Porsche Electronic Parts Catalog) can help you verify. A wrong part might not fit or require adaptation.

Mileage and History

Parts from a low-mileage car (under 100k miles) are generally better. Ask about the car it came from: was it running, was the part functional before removal, any known issues? Honest sellers will share this information.

A Note on Compatibility Across Years

The Porsche 928 had several updates. The most significant split is between early cars (1978–1986) and later cars (1987–1995). Many parts are not interchangeable between these generations. For example, the suspension, brakes, and engine management changed. Always check compatibility using the 928’s model year and VIN. If you are unsure, ask the seller or consult an expert on the forums.

Final Recommendation

For most Porsche 928 owners, the best approach is to start with specialty Porsche recyclers because they offer tested parts with short warranties. Use online forums as a second option for hard-to-find items or for selling parts. Avoid buying critical safety parts like brake calipers or suspension components unless you are confident of their condition. Always ask for photos, part numbers, and function proof. If a deal seems too good to be true, it probably is. With careful hunting, you can keep your 928 running without breaking the bank.
