Before the viewing

A good car comes
with a good file.

Start with the model facts. Then take the inspection checklist to the viewing, so the questions that matter do not get lost in the excitement.

Uwe Riemeyer
Uwe Riemeyer / Founder & Ferrari Owner
Why this exists

Built from the owner’s side.

After selling an FF and a GTC4Lusso through an official Ferrari dealer, Uwe Riemeyer put the combined spread at roughly €40,000. The service was professional. The cost made him look for another way.

Marque brings his ownership experience together with the market research discipline of IMP InterMediaPartners, founded in 1976.

How the research is put together

Public sources only, verified before they enter a file. Model files carry the facts, checklists carry them to the viewing, papers read the market. Reported figures stay marked as reported, nothing is invented, and none of it is investment advice.

Research and private introductions

The research is open to everyone and stays that way. The Room is separate: a personally reviewed circle for collectors who want careful, private introductions, with commission-based intermediation where appropriate.

The Room / By Application

way to buy.

For collectors who value a careful introduction and prefer to keep the conversation private.

Apply for The Room
Who is The Room for?

Collectors and owners who approach this market with research before opinion, full documentation before any sale, and discretion as the default. If that is how you buy, the Room is for you.

Do I need to join to read the papers?

No. The research is open access and stays public either way. The Room only adds the personal layer: introductions, conversations, and vetted cars.

A question about a model?

Ask the research.

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.
