A car must be at least twenty-five years old to be classified as an antique car. Given that cars have been manufactured since the early 1900's, the antique car category covers a broad range of vehicles. To be insured by an antique car insurance company, the car must also be in good condition.Antique car insurance policies cover cars that are primarily used for special events, displays, and functions. Antique cars are frequently seen in parades, car exhibitions, and public events. If a car is regularly driven for basic transportation, it will not qualify for antique car insurance. Antique cars are typically purchased as investments or to further the owner's interest and involvement in a hobby, and these cars are expected to be driven on a much more occasional basis than a personal transportation car. To be eligible for antique car insurance coverage, the car must be a factory original. There can be restorations made to the vehicle, but there should not be any changes to the original factory specifications. Any restorative improvements or modifications made to the antique car must be disclosed at the time the policy is written, as these changes will affect the coverage amount granted for the vehicle.

Unlike the typical personal car that depreciates every year, an antique car will appreciate with age. If the insurer and buyer agree that the antique car is in excellent shape and has the potential for appreciating in value each year, the car's valuation can be completed. The owner needs to have a good idea of the antique car's current market value and also the history of the car's market supply and demand. An antique's car value can fluctuate year to year, and it is the owner's responsibility to ensure the coverage is reset to the most current market value every year.

In general, antique cars are valuable and must be protected from vandalism and theft. A vehicle insured as an antique car must be stored in an enclosed storage area that is secured with a lock. A private garage is the typical storage choice for an antique car, although other storage areas may be acceptable options. If the antique car will not be stored in an approved storage space, the insurance will be denied.The best way to determine if an antique car is suited for antique car insurance coverage is to speak to an insurance company customer representative. Three well-known antique car insurance companies are Hagerty, Grundy Worldwide, and J.C. Taylor.
