Precision Preservation – Under the Hood at 928 Classics

928 Classics is a solo operation—one set of hands and a design-led focus dedicated to your Porsche 928. This isn't a warehouse where parts simply move from a shelf to a box; it is a specialized workshop where every component is handled with the understanding that these cars deserve a factory-original standard of preparation.

My work often involves a deep-dive into early 928 archaeology—identifying, sourcing, and documenting the specific nuances of the 1978 through 1980 models. My focus is on the recherche: the dedicated hunt for the rare and hard-to-find items required to keep a restoration complete, correct, and authentic.

Benchmarked Preparation

The philosophy here is straightforward: if a part doesn’t meet my own expectations, you won't find it on my Parts Store. When something is listed there, it represents hours of cleaning, repair, and restoration. My goal is to ensure that when you open a box, the quality is there and the part is ready for your car. This reputation for quality is how I have earned the long-term trust of owners who value "no-questions-asked" results.

Solving for NLA

For many critical 928 components, Porsche ended production decades ago. My background allows me to step in where the factory left off, applying Product Design principles to develop and offer reproductions that have been No Longer Available (NLA) for years.

Supplying production-level quality to a niche market is a significant challenge. Whether it's hand-fabricated intake tubes or house-designed radio faceplates, nothing here is off-the-shelf—these are custom solutions for owners who understand that when a part is NLA, making it available again requires a different level of effort.

Behind the Bench

The Parts Store is a snapshot of what is ready to ship, but the workshop goes much deeper. On the shelves is a "pre-inventory" currently queued for the bench—a perpetual collection of unlisted items that haven't hit the site yet, simply because they are waiting for the right customers and the right projects.

  • Special Orders:

    If you need more than what is currently listed, just ask. I can put together any custom order for your project—from a single "Uber RARE" find to a complete group of parts pulled from both the storefront and the shelves.

  • Restoration Services:

    If you already have the core but need it made right, you can send it in. I apply the same meticulous preparation to your gauge panels, locksets, and power antennas that I put into everything in the workshop.

  • Sourcing:

    If you are looking for something elusive, let me find it for you. I can set up a Pre Order to secure your position; once it has been located and prepped, it will be at your door before it ever sees the storefront.

A Specialist Connection

Every part that leaves this workshop has been through my hands. Whether it's house-designed reproductions or intricate gauge rebuilds, you are paying for the quality and expertise I bring to my work. I don't ship anything that I wouldn't install on my own cars. This is what has made 928 Classics your Porsche 928 restoration and rare parts specialist.

Jim Doerr is a serious Porsche 928 enthusiast. A product designer and preservationist dedicated to the history of the early Porsche 928, Jim’s work goes beyond simple restoration. He specializes in the archaeology of very early '77 and '78 models, including the documentation and preservation of early pre-production cars such as Press Car Number Sixthe 6th Porsche 928 ever built.
Combining a designer’s eye for detail with a specialized workshop focus, Jim solves the problem of obsolescence by developing house-designed solutions for NLA parts. Whether he is tracing the lineage of a low-vin chassis or restoring a complicated instrument cluster, his goal remains the same: to ensure these early cars stay correct, authentic, and on the road.
