Collector-car research
Are classic cars a good investment?
Classic cars can gain or lose value, and a higher sale price is not the same as a profit. Knight Frank reports classic-car values down 3.7% in 2025. This Passion Asset Advisory guide explains what the evidence measures, how ownership costs change the result and which risks matter before a collector commits capital.

How Passion Asset Advisory reads the return evidence
Knight Frank’s review of the 2025 luxury investment market reports a 3.7% decline in classic-car values during 2025. Its global review published 23 April reports the broader Luxury Investment Index down 0.4% for 2025 and up 38.6% over its reported decade. Those are different series and periods.
| Measure | Period | Published change |
|---|---|---|
| Classic-car values in Knight Frank’s release | 2025 | −3.7% |
| Knight Frank Luxury Investment Index, all covered categories | 2025 | −0.4% |
| Knight Frank Luxury Investment Index, all covered categories | Reported decade through 2025 | +38.6% |

A model valuation also differs from a transaction. Hagerty’s valuation tools distinguish condition and model details. Use that kind of evidence to frame questions, then examine actual comparable cars and their sale terms. An index is not an offer to buy your car.
What does classic-car ownership really cost?
Build a budget from quotes for the particular car and your intended use. Do not apply the same annual percentage to a simple road car and a complex competition machine.
| Stage | Include in the budget |
|---|---|
| Acquisition | Inspection, buyer’s premium or broker fee, tax, import requirements and transport. |
| Annual ownership | Storage, insurance, service, registration, fuel and planned event use. |
| Irregular work | Recommissioning, corrosion or accident repair, major mechanical work and difficult-to-source parts. |
| Exit | Seller’s commission, preparation, transport, any unpaid tax and the cost of waiting for a buyer. |

Collect invoices and record the dates of payments. A restoration bill is money spent, not automatic value added. If a car needs substantial work, establish who can do it, likely lead time, scope and a contingency before deciding whether the purchase fits.
Can a car rise in price while its owner loses money?
Yes. Hypothetical example only: assume a $100,000 purchase, $10,000 in acquisition costs and $8,000 of ownership spending in each of five years. The total cash outlay is $150,000. If the car later sells for $160,000 and the assumed selling cost is 10%, the owner receives $144,000: a $6,000 loss despite a 60% increase in the car’s gross price.
The break-even gross sale price under those assumptions is $150,000 ÷ 0.90 = about $166,667. Taxes on sale, finance costs, inflation and opportunity cost are not included, so economic break-even could be higher. The 10% selling cost is an example assumption, not a quoted car-sale service fee.
Compare investments only after aligning dates, currency and treatment of costs and income. This page does not claim that classic cars outperform a dividend-reinvested stock index or gold.
Which risks can reduce the return?
- Identity and provenance: incorrect chassis claims, missing ownership records or undisclosed rebuilding can undermine a valuation.
- Condition: deferred work, corrosion and a poor restoration may cost more than the apparent purchase discount.
- Market depth: a rare car may have few buyers as well as few rivals. Scarcity does not guarantee liquidity.
- Changing demand: a model favoured by one group of collectors may not attract the same premium later.
- Use and storage: both driving and prolonged inactivity create inspection and maintenance needs.
- Cross-border exposure: currency, import restrictions, taxes and registration requirements can change the all-in cost or buyer pool.
Do not borrow on the assumption that appreciation will cover repayments. Maintain sufficient liquid funds for living expenses and the car’s upkeep. This is general collecting research, not individualised investment, tax or legal advice.
How should you evaluate a particular car?
- Define what you want to own and how you intend to use it.
- Identify the exact version, identity, specification and ownership history.
- Collect dated sale evidence, including unsold lots where relevant.
- Commission an independent specialist inspection and a written work estimate.
- Calculate acquisition, ownership and exit costs under several sale-price scenarios.
- Set a walk-away price and a realistic route to sale if your circumstances change.
For the model-level research, use eight classic and modern-classic candidates to watch. That separate page lists exact models and individual sale examples; it does not duplicate this returns-and-risks argument.
How can record sales and unsold cars coexist?
Results depend on the individual lot, reserve and audience. RM Sotheby’s 1971 Dino 246 GT at Woodcote Park 2026 is marked “Not Sold” against a £250,000–£300,000 estimate. The estimate is not a transaction price, and the absence of a sale is relevant evidence of uncertainty.
At the other end, the most expensive car auction results include exceptional provenance and charity sales. Neither an unsold lot nor a record alone describes every car in the market.
The collector-car purchase checks and car sale route guide explain what to put in a written brief. These are reference guides, not confirmation of an available service. Any adviser’s role, fee and authorised third-party costs need written agreement. No mandate guarantees a buyer, price or appreciation.
FAQ
Classic-car investment questions
Are classic cars a good investment?
Passion Asset Advisory separates price changes from ownership returns. A particular car can rise in price, but profit is uncertain. Purchase and selling costs, storage, insurance, maintenance, taxes and the time needed to find a buyer all affect the result. Buy a car you can afford to own without relying on appreciation.
What do the latest Knight Frank figures say about cars?
Knight Frank’s April 2026 release reports classic-car values down 3.7% for 2025. The wider Luxury Investment Index fell 0.4% in 2025 and rose 38.6% over its reported decade. The composite’s decade figure is not a classic-car return or an owner’s after-cost result.
Do classic cars outperform stocks or gold?
This guide does not establish that claim. A fair comparison needs the same dates, currency and treatment of costs, tax and income. A car price index is not directly comparable with an equity total-return index without those adjustments.
Which classic cars should I research?
Use the separate eight-model candidate list for exact versions and dated auction examples. A place on a shortlist is not a prediction. The condition, identity, history and price of the individual car matter more than a broad model label.
Does a record sale mean the whole market is rising?
No. One exceptional car can sell well while other examples or segments weaken. Record auctions, charity lots, ordinary dealer listings and unsold estimates answer different questions and should not be combined into a single return claim.
How does mileage affect value?
Mileage matters alongside its evidence and the car’s intended use. A low reading does not prove low use or good mechanical condition. Check service records, inspection findings and periods of storage; do not assume every extra mile removes a fixed amount of value.
Can restoration be treated as an investment return?
No. Record restoration spending as a cost. It may improve condition and saleability, but a buyer need not repay it in full. Ask a specialist to distinguish essential work, preservation and discretionary cosmetic changes before commissioning a project.
Are profits on classic cars tax-free?
Tax treatment depends on the country, ownership structure and whether the activity is private collecting or a business. This guide makes no universal exemption claim. Get qualified advice for the purchase, use, import and eventual sale.
