Porsche Insurance for Classic and Collector Porsches

By Jon Merwin, Founder and CEO

Few cars inspire loyalty like a Porsche. In New England we see every kind: a 356 coupe that has been in one family for fifty years, a long-hood 911 that comes out for the first dry weekend in May, a 914 kept as a weekend toy, a 928 rescued from neglect, and late-model GT cars that live under a cover most of the year. Insuring them well starts with knowing which kind of Porsche you have and how you use it.

This guide covers what is specific to insuring a classic or collector Porsche. For how collector car insurance works in general, start with our classic and collector car insurance guide. We shop collector car coverage with carriers including Hagerty, J.C. Taylor, Liberty Mutual, Cincinnati and American Modern, and we’ll confirm eligibility for your vehicle before you rely on a policy.

Which Porsches are treated as collector cars?

Insurers look at condition, value, use and storage more than age alone, but most collector Porsches fall into a few families.

356 (1948 to 1965)

The car that started it all. Coupes, cabriolets, Speedsters and roadsters are valued on originality, body condition and documentation. Many have been restored more than once, so restoration records and photos matter.

Air-cooled 911 and 912 (1964 to 1998)

The early long-hood cars through 1973, the impact-bumper G-series cars from 1974 to 1989 including the 930 Turbo and Carrera 3.2, the 964 and the 993, the last of the air-cooled 911s. Air-cooled 911 values climbed sharply over the last two decades, which is exactly why agreed values need regular review. The 912 four-cylinder cars have their own following.

Transaxle cars and the 914

The 914, 924, 944, 968 and 928 were once bargains and are now collected in their own right, especially low-mileage, original and special models. They are often a good fit for a collector policy when they are no longer daily drivers.

Water-cooled and GT models

Water-cooled 911s and Boxsters and Caymans from the 996 and 986 onward are mostly still used cars, but limited-production and GT models are increasingly treated as collectibles. If you drive one regularly, see high-value auto insurance and our guide to exotic and high-value collector car insurance.

What drives a collector Porsche’s value

Two cars that look the same can be worth very different amounts. When we help set an agreed value, the details below make the biggest difference.

• Matching numbers. An original, numbers-matching engine and transmission usually carry a premium over a replacement.
• Factory documentation. A Porsche Production Specification (which replaced the old Certificate of Authenticity) or factory build records confirm the original color, options and equipment. A Porsche Classic Technical Certificate adds a dealer inspection and confirms whether the engine and transmission numbers match.
• Options and color. Rare factory options, sport packages and paint-to-sample colors can add significant value.
• Manual vs. automatic. Manual cars typically command more in most generations.
• Service history. Complete records, especially for major engine work, support value. On some 996 and 986 cars, buyers ask about documented intermediate shaft (IMS) bearing service.
• Originality and rust repair. How, where and how well rust repair was done matters, especially on early cars.

Bring us whatever documentation you have. Photos, receipts, appraisals and recent sales of similar cars all support the agreed value. Our guide to agreed value car insurance explains how the value is set and kept current.

Backdates, outlaws and other modifications

Porsche owners modify in their own ways: backdating a later 911 to look like an early car, building an outlaw with a bigger engine and modern suspension, adding a roll bar and fixed-back seats for track days, or fitting period-correct performance parts. Some of these builds are worth more than an original car, and some are worth less. Either way, they are usually insured under different rules than an original or restored car. See modified car insurance for how modified cars are handled.

Tell us about every modification up front, with receipts and photos. An undisclosed modification can cause trouble at claim time, and a value that ignores the work you paid for can leave you short.

Driving: clubs, tours and track days

Collector policies are written for hobby use: club drives, tours, shows, concours events and occasional pleasure drives. Porsche Club of America events are a big part of the hobby in New England, from autocross to tours through the White Mountains and the Litchfield Hills.

Driver education and track days at circuits like Lime Rock Park in Connecticut or New Hampshire Motor Speedway in Loudon are a different matter. Collector policies commonly exclude track days, timed events and racing. If you plan to go on track, call us before the event so we can look at separate track day coverage.

Storage and the New England climate

Most owners lay classic Porsches up from late fall until the salt is gone in spring. Porsche began galvanizing 911 bodies in the mid-1970s, so earlier cars are especially vulnerable to rust in the floor pans, battery boxes and longitudinals. A locked, enclosed and dry garage, a battery tender and a breathable cover go a long way. Our guide to collector car storage and winter lay-up has a full checklist, and our spring recommissioning guide covers bringing the car back out.

Some owners keep an all-wheel-drive Carrera 4 or a Cayenne for winter. If a Porsche is your winter car or your daily driver, it usually belongs on a regular or high-value auto policy, not a collector policy.

If you have a claim

Ask whether you can choose your repair shop. Many collectors prefer a Porsche specialist or restorer who knows the car, and finding correct parts for early cars takes time and experience. Use a flatbed for any tow. If the car is a covered total loss, a collector policy with agreed value pays the agreed amount, less any deductible. If you trailer your car to shows or events, see car shows and trailering.

Why work with an independent agency

Specialty insurers look at a Porsche differently, and their rules on use, storage, modifications and value change over time. An independent agency can compare them side by side and coordinate the collector policy with your daily-driver auto insurance, your home insurance and your umbrella policy, so liability limits line up and nothing falls through the gaps.

Portsmouth Atlantic Insurance is a family-owned independent agency founded in 2005. Our 15 employees work from our Portsmouth, NH office and a Connecticut office, we are licensed in 10 states, and we work with 40+ carriers. We are New Hampshire’s highest-rated agency on Google, with 1,000+ Google reviews and over 2,000 testimonials, and we don’t charge any fees.

We work with collectors from our Portsmouth office across New Hampshire, Maine and Connecticut, and in our other licensed states. See our state guides for New Hampshire, Connecticut and Maine.

Frequently asked questions

Can a modern Porsche be insured on a collector policy?

Sometimes. Some insurers will write a limited-production or GT model on a collector policy if it’s used sparingly, stored securely and backed by a separate daily driver. A newer Porsche driven regularly usually fits better on a high-value auto policy. We’ll confirm eligibility for your vehicle and compare both options.

Does a collector policy cover Porsche Club driver education or track days?

Usually not. Collector policies commonly exclude track days, timed events and racing, including driver education events at tracks. Ask us before the event so we can look at separate track day coverage or another option for that day.

Does a Porsche Production Specification or Classic Technical Certificate help with insurance?

They help document the car. A Porsche Production Specification, which replaced the old Certificate of Authenticity, records how the car left the factory. A Porsche Classic Technical Certificate adds an inspection at a Porsche Classic Partner or qualified dealer and confirms whether the engine and transmission numbers match the factory records. These documents, factory build records, matching numbers and service history all support the value you and the insurer agree on, and they make a claim easier to settle if the car is ever a total loss.

Will a backdated or modified 911 cost more to insure?

It depends on the work and the insurer. Modified cars are usually insured under different rules than original cars, and the value has to reflect the build. Keep receipts and photos of the work, and tell us about every modification up front so the policy fits the car.

Can I drive my air-cooled 911 in the winter?

Collector policies are written for hobby use, and most New England owners lay air-cooled cars up for the winter to keep them off salted roads. If you plan to drive the car in winter or often, tell us, because that may point to a different kind of policy.
