Classic car insurance and modified car insurance are often confused — both cover non-standard vehicles and both use specialist insurers. But they are fundamentally different products designed for different types of car and different types of owner. Using the wrong product can mean your claim is rejected, your policy is void, or you’re paying for cover you can’t actually use.
The Core Difference
Classic car insurance is designed for vehicles that are preserved in or restored to original condition. Modifications are generally excluded or restricted — the insurer is covering a car for what it was, not what it’s been changed into.
Modified car insurance is designed for vehicles that have been altered from factory specification for performance, aesthetics, or both. The modifications are the reason you need the specialist cover.

| Modification cover | Period-correct mods only | Performance mods covered |
| Mileage limits | Often limited, insurer-specific tiers | Usually unlimited or higher limits |
| Track use | Usually excluded | Available as add-on with some insurers |
| Storage requirements | Often requires secure storage | Standard security requirements |
| Driver age minimum | Varies by insurer, often higher than standard cover | Varies by insurer |
Which Do You Need for a Restomod?
Restomods — classic bodies with modern drivetrains and suspension — sit in a grey area. They are classic in appearance but modified in specification. The right policy depends on which element is more significant. A 1969 Camaro with a modern LS-family swap on coilovers needs a modified car policy, not a classic car policy. A 1967 Mustang with a period-correct restoration and a mild cam upgrade may suit a classic car policy with a modification endorsement.
Can You Switch Between Products?
Yes — if your car’s specification changes significantly (e.g., you engine-swap a classic car), you should switch to a modified car policy. Continuing on a classic car policy after significant modification can void cover. Contact your insurer before undertaking major work, and see our guides on agreed value vs stated value and declaring engine modifications for the mechanics of doing this properly.
Frequently Asked Questions
Can a modified car get agreed value insurance?
Yes. Agreed value is available for modified cars through specialist insurers. The agreed value must include the cost of modifications, not just the car’s standard market value. Documentation (receipts, photos, dyno sheets) is required to support the agreed figure.
Does classic car insurance cover track days?
Generally no. Classic car policies are designed for road use and shows — track days are excluded. If you use a classic car on track, you need either a modified car policy with a track endorsement, or a standalone track day insurance policy — and either way, confirm the exact scope directly, since coverage details vary by insurer.
What counts as a classic car for insurance purposes?
Definitions vary by insurer and country — 25 years old is a commonly used threshold, but not universal. Classic car insurance products focus on originality rather than age alone — a preserved original car is what they are designed for, not a modified older car.
