Classic Car Price Guide vs a Valuation Report: Which?

Published 14 October 2026 · 6 min read

A classic car price guide gives a typical value for a model, year and condition grade. A valuation report gives the value of your own car on a stated date, with the comparable cars and adjustments written down. A guide is enough to get a feel for the market. It is not enough when HMRC, an insurer or a solicitor has to accept the figure.

This guide uses the Hagerty Price Guide as the example, because it is the one most owners meet first, and sets out what it tells you, what it cannot, and the cases where a report is the safer choice.

What does a classic car price guide actually tell you?

It tells you what cars of your type typically sell for, by condition. Hagerty says its UK values come from classic car auction activity, classic car dealers, private sale values reported by its insured clients, and a constant review of the estimated values on the UK's classic car websites. Its valuation tool says it covers over 50,000 UK classic and collectible car values and that the guide is updated quarterly.

The value you read is tied to one of four condition grades, which Hagerty defines like this:

Grade	Hagerty's description
#1 Concours	The best in the world: the best car, unmodified, in the right colours, driving onto the lawn at the finest concours
#2 Excellent	Could win a local or regional show; seasoned observers have to look closely for flaws
#3 Good	Some, but not all, of the issues of a #4 car, balanced by other factors such as a fresh paint job or a new, correct interior
#4 Fair	Daily drivers, with flaws visible to the naked eye, such as pitted or scratched chrome

Where does a price guide stop being enough?

A guide describes a type of car. It does not describe yours. The grade definitions above are about how the car looks and how well it has been kept; the four descriptions do not mention mileage, owner history, documents, modifications or an import history, which are exactly the things that move the price of one example against another. Choosing the grade is also left to you, and the difference between a #2 and a #3 car is a judgement call.

The date is the second gap. A guide updated quarterly shows the market as it stood at the last update, not on the day you need. If you need the value on a past date, such as the date of death for probate, the guide does not give you that.

Price guide or valuation report: what is the difference?

	Price guide	Valuation report
What it values	A type of car at a condition grade	Your car, with its mileage, history and condition
Date	The latest quarterly update	The date you need, such as a date of death or the start of a policy
Basis	Whatever the guide measures, summarised in one figure	The basis the purpose needs, such as open market value for probate
Working shown	Sources described in general terms	The comparable cars and the reason for each adjustment
Who can check it	You can look it up; the reasoning for your car is not there	HMRC, an insurer or a solicitor can follow how the figure was reached

Our guide to what makes a valuation report defensible explains why that last row matters: a figure with a visible trail survives a challenge, and a figure with none has nothing to point to.

When is a price guide fine?

For getting a feel for the market, checking a seller's asking price before you view a car, or deciding whether to insure for more than you thought, a guide is quick and free. It is a reasonable first look. The point is to stop treating the figure as evidence once someone else has to rely on it.

When do you need a valuation report instead?

• Probate. HMRC's inheritance tax rule is that an asset is valued at the price it might reasonably be expected to fetch if sold in the open market at that time (HMRC, IHTM09703). That is the date of death and the car's actual condition, which is what our guide to open market value for probate covers.
• A valuation made on the wrong basis. HMRC says it usually accepts a professional valuation of household and personal goods prepared on an open market value basis, and warns that one prepared on another basis may not meet the legal test. Its example is a valuation for insurance purposes on replacement values, which can overstate the value (HMRC, IHTM21041). The same applies to a guide figure that was built for another purpose.
• An insurance dispute. The Financial Ombudsman Service says the main trade valuation guides do not usually value vehicles over 20 years old, and asks for other evidence in that case. Our guide to the valuation guides insurers use for a write-off sets out what it accepts.
• Agreed value cover. Insurers decide what they accept as the agreed figure, and many ask for evidence. See insuring a modified, imported or classic car.
• Divorce or a dispute with another party. When the other side can query the number, the working has to be there.

How do you use a price guide well?

1. Pick the condition grade honestly, and write down why you chose it.
2. Note the date of the guide update you read, and save a copy of the page.
3. Compare the figure with current adverts for cars like yours, matching year, mileage and specification.
4. If the figure will be given to HMRC, an insurer or a solicitor, ask what basis and what evidence they need before you rely on it.

Frequently asked questions

Is a classic car price guide a valuation?

No. A price guide such as the Hagerty Price Guide gives typical values by make, model, year and condition grade. A valuation report values your own car on a stated date, with the comparable cars and the adjustments shown.

Will HMRC accept a price guide figure for probate?

HMRC asks for the open market value on the date of death, in the car's actual condition. A guide figure can help you form a view, but it is a typical value, not a value for your car on that date. For anything unusual or valuable, HMRC advises a professional valuation.

How often is the Hagerty Price Guide updated?

Hagerty says the UK Price Guide is updated quarterly. A value you read today may therefore not match the date you need, such as a date of death or the start of a policy.

Can I use a price guide to argue with an insurer?

It can support your case, but a single guide figure is a weak basis for a classic. The Financial Ombudsman Service says the main trade guides do not usually value vehicles over 20 years old, so it asks for other evidence such as an engineer's report or comparable adverts.
