Getting a defensible number on a classic or modified car

Why agreed value matters

Most standard policies insure a vehicle for market value, which the insurer determines after a loss. On an ordinary car that is usually fine. On a classic, a restored car or a heavily modified one it can be badly wrong, and the moment you discover it is the worst possible moment.

An agreed value fixes the figure in advance, in writing. Insurers will generally only offer one against an independent valuation, because otherwise they are accepting the owner's own estimate of a vehicle they cannot easily price.

Because the market moves and policies renew, agreed values get revisited. A certificate states the value at a specific date and is valid for 28 days, so most owners obtain a fresh one when their policy comes up rather than relying on an old figure.

How condition is assessed

On a classic, condition is most of the value. The same model can span an enormous range between a concours restoration and a running project, and the difference is not linear — the last increment of condition is usually the most expensive to buy and the most valuable to hold.

Originality is assessed alongside it: matching numbers where that applies to the model, factory specification, the quality and reversibility of any changes, and whether the documented history supports what the car appears to be.

Restoration and modification receipts matter, and not because money spent equals value gained — often it does not. They matter because they evidence what was actually done, by whom, and when.

Modified vehicles

Modified cars are routinely undervalued by guides and overvalued by owners, and the truthful figure is usually neither. A professionally engineered build with certification and receipts is a different asset to an equivalent car with undocumented work, even where the parts list reads the same.

Where modifications require engineering approval or affect compliance, that documentation forms part of the assessment. As an ISO 9001 certified, SAI Global registered automobile workshop, compliance is familiar ground for us rather than something read off a form.

Estates, settlements and sales

Classic vehicles turn up in deceased estates and property settlements more often than their numbers suggest, usually because they are the asset nobody can agree on. An independent figure with documented reasoning tends to end that argument faster than three opinions from enthusiasts.

In a private sale a valuation does a simpler job: it gives a buyer something other than the seller's word, which on a high-value car is often what closes the gap.

Common questions

What do I need for an agreed-value insurance valuation?

The vehicle details and VIN, odometer, photographs inside and out, and any documentation of restoration, modification or history. The more evidence of condition and originality, the tighter the figure.

How often should a classic be revalued?

A certificate states the value at a specific date and is valid for 28 days. Most owners obtain a fresh valuation when their policy renews, since values on collector vehicles move and an out-of-date figure is the one that disappoints after a loss.

Do modifications add value?

Sometimes, and rarely by what they cost. Quality, documentation and how well the work suits the platform matter more than the spend. Undocumented work is generally assessed more conservatively than the same work with receipts and engineering approval.

Can you value a car that isn't running?

Yes. A project or unregistered vehicle still has a defensible market value, and estates and settlements frequently require exactly that. Condition is assessed from evidence rather than assumed.

Is the certificate accepted for probate or a property settlement?

Our certificates are signed by an experienced valuer and prepared to professional standards accepted by Australian banks, insurers, government agencies and family law courts.
