New Hampshire
Collector Car Insurance
Call Us: 603-766-3733
A 1967 Corvette Stingray sits in a heated Wolfeboro garage from November through April, then runs Lake Winnipesaukee back roads on summer Saturdays. The owner assumes his standard auto policy will respond if a hailstorm rolls through, or if a deer puts the car in a ditch outside Hanover. It won’t, at least not for what the car is actually worth. Standard auto policies use a depreciation formula that bears no relationship to what a numbers-matching Stingray brings at auction, and that gap between book value and market reality is precisely where most New Hampshire collectors get burned after a loss. This guide breaks down agreed value coverage across five specialist and HNW carriers available to NH collectors, Hagerty, Grundy, American Modern, Chubb, and Berkley One, explains how New Hampshire’s regulatory environment and winter climate may shape your policy, and helps you match the right carrier to the value and use profile of your collection.
The Essentials of Collector Car Insurance in New Hampshire
New Hampshire stands out among U.S. states for its insurance flexibility. It’s one of the few states that doesn’t mandate auto liability insurance for all drivers, though financial responsibility laws still apply if you cause an accident. For collector car owners, this creates both opportunity and risk. You have more freedom in structuring your coverage, but you also carry more personal exposure if something goes wrong. Understanding the specific tools available for insuring classic, antique, and high-value vehicles in the Granite State is the foundation of protecting your investment.
How Agreed Value Coverage Differs from Actual Cash Value
Standard auto policies use actual cash value (ACV), which factors in depreciation. For a daily driver, that’s annoying but tolerable. For a collector car, it’s a disaster. A frame-off restoration on a 1970 Plymouth ’Cuda might cost $150,000 or more, but an ACV policy could value it at a fraction of that based on age alone. Agreed value coverage solves this by locking in a pre-determined payout amount at policy inception. You and the insurer agree on what the car is worth, supported by appraisals and market data, and that’s the amount you typically receive in a total loss, no haggling, no depreciation deductions.
The difference in annual premium is often surprisingly small. A collector car insured for $75,000 on an agreed value basis might cost $300 to $600 per year, compared to $1,200 or more for a standard policy with inferior coverage. The savings come from usage restrictions and the lower risk profile of carefully maintained vehicles driven limited miles.
New Hampshire State Requirements for Classic and Antique Plates
New Hampshire offers antique plates for vehicles that are at least 25 years old under RSA 259:4, which exempts them from standard inspection requirements. This is a meaningful benefit for collectors running period-correct equipment that might not pass modern safety standards. Antique-plated vehicles are intended for exhibition, club activities, parades, and occasional pleasure driving rather than daily commuting.
Most collector car insurers align their policies with these usage expectations. If you register a vehicle with antique plates, your insurer will generally expect it to be driven fewer than 2,500 to 5,000 miles annually and stored in an enclosed structure. Violating these terms can jeopardize coverage, so it’s critical to match your registration type with your actual driving habits.

Specialist Providers: Hagerty, Grundy, and American Modern
The three most recognized specialist names in collector car insurance each bring different strengths to the table. Choosing between them depends on the size and value of your collection, how often you drive, and what kind of support you want beyond the policy itself.
Hagerty: Valuation Tools and the Drivers Club Network
Hagerty is one of the dominant specialist carriers in the collector car market, and for good reason. Their valuation tools draw on one of the largest databases of classic car transaction data in the world, which means your agreed value is grounded in real market evidence. Their Drivers Club membership may add roadside assistance from flatbed-equipped providers who understand that your car shouldn’t be towed with a wheel-lift, plus access to curated events and a community of fellow enthusiasts.
For NH collectors, Hagerty’s strength lies in their familiarity with seasonal storage patterns and their willingness to insure cars that are actively enjoyed rather than just parked in climate-controlled garages. Policies may allow pleasure driving and club events without the rigid mileage caps some competitors impose. As with every carrier, the specific terms depend on the form issued.
Grundy and American Modern: Traditional and Modern Classic Appetite
Grundy has been writing collector car policies since the 1940s and is widely credited with pioneering agreed value coverage in the United States. Their program may be a strong fit for NH owners of more modestly valued classics (a clean Mustang, a solid MGB, a well-kept 1950s pickup) where the agreed value typically sits in the $15,000 to $75,000 range. Grundy also tends to be straightforward on transport coverage to local shows like the Concord d’Elegance or the New England Concours d’Elegance in Sunapee.
American Modern fills a different niche, extending coverage to modified and custom vehicles that some traditional carriers won’t touch. If you’ve built a restomod with a modern LS engine in a classic body, or you own an early 1990s air-cooled Porsche 911 that’s surged in value over the past decade, American Modern is often more receptive than purist-oriented insurers. Their program may also cover newer “modern classics”, E30 BMW M3s, first-generation Acura NSXs, that fall into the gap between standard auto and traditional collector policies. For NH collectors who bought a clean 964 Turbo for $60,000 a few years ago and now own a $180,000 car, getting that updated value locked in isn’t optional, it’s urgent.

High-Value Asset Protection with Chubb and Berkley One
When a single vehicle in your collection exceeds $500,000, or when the total collection value reaches into the millions, the conversation shifts from specialty auto insurance to comprehensive asset protection. Chubb and Berkley One operate in this space, treating collector cars as one component of a broader wealth management strategy alongside the home, umbrella, and personal lines coverage you already carry through Avery.
Concierge Claims Handling for Multi-Million Dollar Collections
Chubb’s claims process for high-value collector cars is fundamentally different from what you’d experience with a standard carrier. They typically assign dedicated adjusters with expertise in collector vehicles, may coordinate with marque-specific restoration shops, and may authorize the use of original or NOS parts rather than aftermarket substitutes. For a car worth $2 million, the difference between a proper restoration and a botched repair can swing six figures.
Berkley One has expanded its private-client appetite to include high-value collector vehicles in recent years. Their program may offer competitive agreed value terms and underwriting attention that often rivals more established HNW markets, and can be a strong fit for NH owners who want to consolidate home, auto, umbrella, and collector car coverage under a single private-client relationship. An agency like Avery Insurance, with over 125 years of experience placing coverage with carriers like Chubb and Berkley One, can help ensure your collection is properly appraised and placed with the right underwriter from the start.
Flexible Use and Worldwide Coverage Considerations
Both Chubb and Berkley One may offer worldwide coverage options when the vehicle is scheduled appropriately, relevant for NH collectors who ship a car to a European rally, display at an international concours, or send a vehicle to auction overseas. Standard specialist policies from Hagerty or Grundy typically restrict coverage to the U.S. and Canada. For collectors who participate in events like the Goodwood Revival, the broader navigation language some HNW forms may include is essential. Coverage may extend worldwide depending on the form issued, and the specific terms vary by carrier and underwriting decision.
These carriers also tend to be more flexible about flexible-use language. If you want to drive your Ferrari 250 GTO to dinner at a Portsmouth restaurant on a summer evening, Chubb and Berkley One are typically less likely to quibble about whether that qualifies as “exhibition use” than a budget-tier specialty carrier might be. As always, the actual scope of flexible use depends on the policy form issued.
Storage Requirements and Mileage Limitations
Every collector car insurer requires enclosed storage, typically a locked garage or dedicated storage facility. A carport doesn’t count. If you’re storing vehicles in a barn or detached building (common in rural NH towns like Sunapee or New London) insurers will want to know about security measures: locks, alarms, and sometimes even fire suppression systems for high-value collections.
Mileage limits vary by carrier and policy tier. Most range from 2,500 to 7,500 miles annually, with some carriers offering unlimited mileage options at higher premiums. Be honest about your driving habits during the application process. An insurer who discovers you’ve been daily-driving a car insured under a 2,500-mile policy has grounds to dispute a claim.
Handling New Hampshire’s Seasonal Climate and Winter Storage
New Hampshire’s winters are brutal on collector cars. Road salt, freeze-thaw cycles, and moisture create conditions that can destroy undercarriages, rot floor pans, and corrode brake lines in a single season. Most NH collectors store their vehicles from November through April, and insurers expect this. Seacoast collectors in Portsmouth, Rye, and Hampton face an additional salt-air corrosion exposure that inland collectors don’t, and underwriters may ask about garage construction and dehumidification when binding coverage near the water.
A proper winter storage protocol includes a battery tender, fuel stabilizer, tire cradles or overinflation to prevent flat spots, and a breathable car cover in a climate-controlled space. Some insurers offer reduced premiums during storage months if you declare the vehicle as “laid up,” removing collision and liability coverage while maintaining comprehensive protection against fire, theft, and weather damage. Lay-up endorsements may reduce annual premiums by 20% to 40%, depending on the carrier and the months declared.
Selecting the Right Policy for Your NH Collection
The right collector car insurance policy depends on what you own, how you use it, and what keeps you up at night. A single well-maintained classic worth $30,000 is a straightforward placement with Hagerty or Grundy. A multi-million-dollar collection that includes international show cars typically demands the white-glove treatment of Chubb or Berkley One. And that appreciating modern classic in your Bedford garage may need an insurer like American Modern that understands its trajectory.
Working with an independent agency like Avery Insurance gives you access to all of these carriers through a single relationship, with advisors who can evaluate your entire portfolio of assets (home, auto, liability, and collections) as a unified risk profile. That kind of holistic review often uncovers gaps that single-carrier shoppers miss entirely. Your collection represents decades of passion, knowledge, and investment. Protect it with coverage that reflects its true worth. Request Coverage through Avery Insurance to get started.
Frequently Asked Questions
DDo I need auto insurance to register a collector car in New Hampshire? New Hampshire doesn’t require liability insurance for vehicle registration, but you’re financially responsible for any damage you cause. Carrying agreed value coverage with appropriate liability limits protects both your car and your personal assets.
Can I insure a modified or restomod vehicle under a collector car policy? Yes, but carrier appetite varies. American Modern is generally the most receptive to modified vehicles, while Hagerty and Grundy typically prefer stock or period-correct restorations. Chubb and Berkley One may consider modified vehicles on a case-by-case basis.
How often should I update my agreed value? Review your agreed value annually or whenever the market shifts significantly. Cars that have appreciated 50% or more since your last appraisal may be dangerously underinsured.
What happens if I exceed my mileage limit? Most insurers won’t automatically deny a claim, but exceeding stated mileage could give them grounds to dispute coverage. Always report changes in usage to your agent promptly.
Is winter storage coverage cheaper than year-round coverage? Typically, yes. Declaring a “lay-up” period (removing collision and liability while keeping comprehensive) may reduce your annual premium by 20% to 40%, depending on the carrier and the months declared.
Does my collector car policy cover shipping to a European rally or concours? Sometimes. Specialist carriers like Hagerty and Grundy generally restrict coverage to the U.S. and Canada. Chubb and Berkley One may offer worldwide coverage when the vehicle is scheduled appropriately, but the specific terms depend on the form issued and the underwriting decision.

Got Questions? We’ve Got Answers.
Straight Answers From the Advisors Who Know This State Best
What does it mean that Avery is an independent insurance agency?
An independent agency like Avery is not tied to any single insurance company. We represent multiple top-rated carriers, which means we can shop the market on your behalf and recommend the coverage that truly fits your needs — not the one that benefits any single insurer.
This independence gives you access to more options and unbiased advice. Our advisors are compensated to serve your interests, not to push a specific product. That is a significant advantage over captive agents who can only offer one carrier’s policies.
How much does it cost to work with an Avery advisor?
There is no direct cost to you for working with an Avery advisor. Independent agents are compensated through commissions paid by the insurance carriers when a policy is placed. You receive expert guidance, market comparisons, and ongoing service at no extra charge.
In fact, many clients find that working with Avery saves them money. Our advisors know how to identify the right coverage levels so you are not paying for protection you do not need, and you are not left exposed where you do.
Does Avery help with claims?
Yes — and this is one of the most important things that sets Avery apart. When you have a claim, our in-house claims advisors go to work for you. We guide you through the process, communicate with the insurance company, and advocate for a fair and timely outcome.
Several of our team members hold professional claims designations, including AIC and AINS. We do not just help you file paperwork — we actively represent your interests to make sure you receive the full benefit your policy provides.
Where in New Hampshire does Avery provide coverage?
Avery serves clients throughout the state of New Hampshire from our offices in Wolfeboro and Portsmouth. Whether you live in the Lakes Region, the Seacoast, the White Mountains, or the Merrimack Valley, an Avery advisor is ready to help you find the right coverage.
Our advisors understand the specific risks that come with living and doing business in New Hampshire — from harsh winter weather to seasonal watercraft exposure. We apply that local knowledge to every coverage recommendation we make.
How does Avery handle high-value homes and assets?
Avery offers a dedicated Premier Client Services program for clients with homes valued over .5 million, significant investment portfolios, fine art collections, jewelry, yachts, and other complex assets. This program pairs you with a specialist who understands the unique risks of high-net-worth households.
Through carriers that specialize in high-value personal lines, we provide guaranteed replacement cost coverage, agreed value policies, and comprehensive risk management strategies. Your advisor will conduct a detailed review of your full asset portfolio to make sure nothing is overlooked or underinsured.
How often should I review my insurance coverage?
Avery recommends a full coverage review at least once a year. Major life events — buying a home, starting a business, adding a vehicle, getting married, or making significant home improvements — are all good triggers for an immediate review outside your annual cycle.
Insurance needs change over time, and policies that were right for you a few years ago may leave gaps today. Avery advisors proactively reach out to clients for annual reviews and keep up with changes in the insurance market that could affect your coverage or premium. Our goal is to make sure you are always protected and never paying for coverage that no longer fits.
