Key points
- The value of a classic car depends as much on its file as on the car itself.
- The service record, restoration invoices and proof of matching numbers weigh on the market value.
- An up-to-date file serves classic car insurance, resale and succession.
Classic car maintenance: what to keep track of
An old car is judged on its parts: those in the engine and those in the folder. Two examples of the same model can have very different values depending on whether one has a complete history and the other twenty-year gaps. Keeping the file for your classic cars means noting each job, keeping each invoice and keeping track of successive owners.
Deadlines matter too: roadworthiness test, insurance policy, annual service, winter storage. A forgotten date can immobilise the car or leave a gap in cover.
What a classic car record contains
| Field | What it is for |
|---|---|
| Make, model, date of first registration | Identify the car and place it within the production run. |
| Chassis number (VIN), registration plate, registration certificate in the name of | Prove the identity and ownership of the car. |
| Engine number, matching numbers | Check that the components are original, a key criterion of value. |
| Fuel, gearbox, engine capacity, original colour | Describe the factory specification; spot a modification. |
| Mileage | Track the use of the car and date each service. |
| Roadworthiness test valid until | Do not let the deadline pass. |
| Restoration history, expert file | Trace the work done and its supporting documents. |
| Maintenance and restoration costs | Know the real cost of the car and justify the work. |
| Provenance and successive owners | Reconstruct the history of the car, which matters for its market value. |
Motorcycles and historic vehicles have their place in the same category, with the same fields.
The service record and the documents to file
The original service record is precious, but it is not enough: add a dated list of all jobs, with the mileage, the garage and the invoice. Store in the same place the registration certificate, including the collector’s registration certificate (carte grise de collection) if the car has one, the roadworthiness test reports, certificates of origin, expert reports and photos of each stage of restoration. Keep the originals in a safe place and a digital copy away from the garage.
Classic car market value, worth and insurance
The market value of a classic car gives an order of magnitude for a model; the value of your car depends on its condition, its originality and its file. Keep the history of valuations, dated and signed, to follow the change in value.
For insurance, policies specialising in collector vehicles may offer an agreed value (valeur agréée), set on the basis of an expert valuation. Our guide agreed value or declared value explains the difference in the event of a claim. Have this value reviewed after a major restoration: an underinsured car is poorly compensated. In the event of theft, the chassis number, photos and invoices will be your first evidence.
Succession
A classic car passed on without its file loses part of its value, and the heirs often know neither which garage it is entrusted to, nor what it is worth, nor whom to contact to sell it. A complete file, with your wishes and the contact details of the garage, the expert and the model’s club, simplifies their task. For the value to use in the estate, consult your notary (notaire); our estate inventory template can serve as a basis.
Photos from your phone and sharing
Photograph the car from every angle, then the engine bay, the plates and number stampings, the interior and the odometer. For a sale or an expert valuation, share the file with the buyer or the expert through a password-protected, time-limited link, rather than sending invoices and chassis numbers by messaging app.
