Why this room exists

I built this for myself first.

When I sold my last two Ferraris, an FF and a GTC4Lusso, I faced the choice every owner knows. The open classifieds meant test-drive tourists, time-wasters, and the genuine criminal element that circles this market. So I did what a careful owner does: I sold through an official Ferrari dealer. The experience was professional, the people were good, and the same network later helped me find the 488 GTB I drive today.

It also cost me roughly €40,000: the spread between what the cars were worth and what a dealer can pay. That is not an accusation. Dealers carry showrooms, staff, stock risk and warranty obligations; the spread is the honest price of their convenience. But it is a price, and I decided I no longer wanted to pay it, and that the open market was no alternative.

So I built the third option: a quiet room of vetted people who document their cars properly and trade among themselves: discreetly, at a fraction of the cost, to one standard.

I am not selling a service here. I am sharing the standard I built for my own cars: research before opinion, full documentation before any sale, personal vetting before anyone enters, and discretion as the default. If you approach this market the way I do, and you are tired of choosing between the spread and the circus, this room is for you. If not, the research stays public either way.

The Research Library

Fifteen marques. One method. Open to everyone.

Model-level market papers, factual model files and pre-purchase inspection checklists: 133 papers, 122 model files and 116 PPI checklists, organised model by model. Every claim sourced, every figure from the public record. Pick a marque.

Owner's Intelligence

Lived experience, documented.

The papers read the market; this section reports from inside it. First-person accounts of buying, owning and walking away, written from the author's own process, with the numbers left in. New reports publish here first, open to everyone.

The Twin

Ask the library a question.

Every paper, model file and checklist in this house, wired into one assistant. Ask what a service gap means, what a clutch costs, where a model's risk sits: it answers from the research, in plain language.

What we do

Three disciplines. One standard.

Market Reports

Model-level research papers: positioning, production context, transaction signals and depreciation curves, built from public listings and documented methodology.

Ownership Intelligence

What these cars actually cost to keep: service intervals, known weak points, parts exposure, insurance logic. The numbers sellers don't volunteer.

Private Intermediation

Discreet, commission-based introductions between vetted collectors. No listings, no auctions, no public record. Available to members only.

Data first. Blunt over smooth. Public sources only, assumptions flagged in grey. The collector market runs on stories. we publish the numbers underneath them.
Editorial standard, applied to every paper since No. 01
What this is built on

A research discipline, applied to a market that runs on stories.

Marque Intelligence did not start from nothing. It is a venture of IMP InterMediaPartners, a B2B market-intelligence firm in Wuppertal founded in 1976, a house that spends its working life reading industrial markets for clients who cannot afford to guess where the next move comes from.

That is the same discipline applied here: read the data before the opinion, source every claim, separate what sold from what someone hoped it would. Chemistry, pharma, petfood, automotive: the sectors IMP reads all sit on the same principle the collector market forgets. A market pivot usually announces itself in the numbers long before it shows up in the talk.

I have been inside the Ferrari world since childhood, and inside serious B2B intelligence for nearly three decades. Marque is where those two finally meet: the enthusiast's eye, held to the analyst's standard.

House Rules

Respect is the entry fee.

The internet has made contempt cheap. Forums where every honest question is met with scorn; comment sections where strangers speak to each other in ways they never would across a table. We are not importing that culture here.

This house runs on one standard: argue hard about cars, never about people. Disagreement is welcome: it is how good judgment gets made, and our papers invite it. Condescension, ridicule and personal attacks are not. Toward anyone: members, sellers, or the newcomer asking the question you stopped asking twenty years ago.

01 Critique the car, the price, the argument. Never the person. A weak argument deserves a better argument, not a verdict on whoever made it.
02 Every question is a serious question. Everyone in this room started somewhere. The day questions become embarrassing here is the day this room has failed.
03 Discretion is mutual. Cars, prices, names: what is shared in the room stays in the room. The same standard that protects you protects everyone else.

None of this is a preference, an aspiration, or a code we enforce reluctantly. Inside the Room it is a condition of membership, the same way the vetting is. On the open site it is the price of being answered.

If that reads as strict, we understand. Then this is not your room, and we would genuinely rather you didn't apply. We will always choose a smaller room over a louder one.

The Room · by application

A vetted room, not a mailing list.

The research is open to everyone. The Room is not. Membership is personal, reviewed individually, and deliberately small. Every applicant is vetted: ownership history, references, conduct. No burnout crowd, no flippers, no anonymous accounts.

Members receive the room itself: the vetted circle, direct exchange among documented owners, invitations to curated drives and closed gatherings, and, where appropriate, access to private intermediation. The research is not the product here; the company is.

There is no public price list and no instant checkout. Apply, and we talk first.

The application takes three minutes. It is read by a person, answered by a person, and usually followed by a conversation, and that conversation is the door.

No public price list, no instant checkout. Apply, and we talk first.

Applications are reviewed personally. Expect a reply, not an autoresponder. Your details are used for the review only; see the privacy policy.

The founder, off the record

Beyond the research.

Showroom mornings, details, the cars themselves: a private lens, kept deliberately separate from the dossiers. Unscripted, unaffiliated, on my personal channels.
