When searching for a classic 911, you will likely encounter three distinct categories: Restoration, Backdate, and Porsche restomod.

While these terms are often used interchangeably, they represent three very different philosophies. Understanding the distinction—specifically between a cosmetic backdate and a fully re-engineered Porsche restomod—is key to defining your perfect build.

At Shoreline 911, we are unique in that we specialize in all three. Whether you are a purist seeking factory-correct perfection or a driver wanting the vintage aesthetic of a Porsche restomod with modern power, we have a pathway for you.

Here is the definitive guide to the three paths of Porsche ownership.

1. The Porsche 911 Backdate: The Best of Both Worlds

The Philosophy: "Vintage aesthetic, modern engineering."

A 911 backdate is the art of time travel. We take a later, more advanced model—typically a Porsche 964—and surgically alter the exterior to resemble the "golden era" of the 1960s and early 1970s.

The Look: Long hoods, slim bumpers, chrome accents, and the classic "wide-hip" silhouette.
The Drive: Because the foundation is a modern chassis, you get power steering, coil-over suspension, advanced braking (ABS), and a more powerful 3.6L or 3.8L engine.
Who is it for? The driver who loves the Steve McQueen aesthetic but wants a car that starts every time, stops on a dime, and can be driven aggressively on modern roads.

2. The Porsche 911 Restomod: The Wolf in Sheep's Clothing

The Philosophy: "Original skin, evolved soul."

Unlike a backdate, a Restomod (Restoration + Modification) generally keeps the car looking like the era it was born in. If we start with a 964, it leaves looking like a 964. However, beneath the surface, everything is upgraded.

The Upgrades: We might install a custom interior with modern Recaro seats, a re-engineered HVAC system for real air conditioning, LED lighting, and a high-performance engine tune.
The Goal: To make the car "usable" in a modern context without altering its historical identity.
Who is it for? The enthusiast who loves the distinct look of the 90s but wants to remove the 30-year-old limitations regarding comfort and performance.

3. The Authentic Restoration: The Time Capsule

The Philosophy: "Exactly as it left Stuttgart."

For the purist, there is no improvement on perfection. A Full Restoration is a forensic process devoted to authenticity, provenance, and history.

The Process: We strip the car to a bare metal shell. Every bolt is plated, every panel is aligned to factory gaps, and the engine is rebuilt to original factory specifications.
The Details: We use period-correct paint codes, source original "new old stock" (NOS) parts where possible, and refurbish the interior using authentic German weaves and leathers.
Who is it for? The collector and the investor. These cars are built to win Concours d'Elegance events and preserve automotive history for the next generation.

The Shoreline Difference: Why Choose?

Many workshops are "one-trick ponies"—they only do outlaw builds, or they only do factory restorations. The Shoreline difference is our flexibility.

Authenticity for Collectors: We have the technical manuals and sourcing network to execute investment-grade restorations.
Creativity for Drivers: We have the engineering capability to build 350HP backdates that chase down modern sports cars.

Which path is right for you?

If you want to preserve history, choose Restoration. If you want to reimagine it with classic style, choose a Backdate. If you want to drive a legend with modern comfort, choose a Restomod.
