Terms of service

Last updated 2 September 2026.

What this service is

Car Deal Finder searches public collector-car listings and estimates what vehicles are worth by comparing them against completed sales it has collected. It also keeps a private garage where you record the cars you own.

It is a research tool. It is not a broker, a dealer, an auction house, or an investment adviser, and it never takes part in a transaction between you and a seller.

Valuations are estimates, not advice

Every figure on this site is derived from sales data we have gathered and is shown with the number of sales behind it. Where a segment has too few sales, we say so instead of producing a number.

An estimate is not an appraisal and not a promise of what any car will sell for. Do not buy or sell a vehicle on the strength of a figure here alone. Inspect the car, read its history, and take professional advice.

Your account

You need an account to search. You are responsible for keeping your password to yourself and for what happens under your account.

One free search comes with a free account. Beyond that, searching, market watches, studio plates and 3D models require a membership.

Membership and payment

Memberships renew automatically for the period you chose until you cancel. You can cancel at any time from Settings; cancellation stops the next renewal and returns you to the free plan.

Atelier credits are bought outright, do not expire, and are not refundable once the GPU work they paid for has run.

Payments are handled by Stripe. We never see or store your card details.

• Collector — $19.99 per week or $49 per month
• Concours — $490 per year
• Atelier credits — 10 for $29

What you may not do

• Resell, redistribute or scrape our valuation data as a dataset.
• Share one account between several people, or automate access to it.
• Upload photographs you have no right to use.

Your content

The photographs, prices and notes you add to your garage stay yours. You grant us only the permission needed to run the service: to store them, and to process them on our own machines when you ask for a catalogue plate or a 3D model.

We do not use your garage to train models, and we do not sell it.

Availability

This is a beta. Features change, searches sometimes fail, and the GPUs that produce plates and 3D models are shared, so that work can queue. The service is provided as it is, without warranty.

Our liability is limited to the amount you have paid us in the twelve months before a claim.

Ending the agreement

You can delete your account at any time by writing to us; we remove your garage, watches and generated images. We may suspend an account that breaks these terms.
