Your passion deserves counsel to match
Collexium Advisory supports discerning collectors in every decision — from the initial analysis to the full management of their collection.

Decision Report
You have found the model — or the specific car. Before committing, one question remains: is it the right choice?
Model scope — you come with an idea
You are considering a specific model but have not yet identified an example. We analyse the segment, compare alternatives, assess market timing and define the selection criteria that distinguish an exceptional example from an ordinary one. You leave with a clear roadmap to search — or to entrust the search to us.
Example scope — you come with a car
You have identified a specific car. We scrutinise the file: authenticity, history, condition-to-price coherence, red flags, foreseeable post-purchase costs, seller reliability. You receive a substantiated recommendation: buy, negotiate, or walk away.
What you get
- —The certainty of deciding on facts, not on the excitement of the moment
- —A clear view of the fair price and true ownership costs
- —The assurance that no blind spot has been overlooked
One-off. Approximately 5 days
From €2K (Model) / €3.5K (Example) — fixed fees. Bespoke quote above €500K.

Bespoke Execution
You know what you want. You know some market players — but are they working in your interest? When you need to identify the best specialist for a precise task, knowing whom to trust is a profession in itself.
We take charge of the entire acquisition process. From the search — including the private market and networks inaccessible to the public — to handing over the keys. The Decision Report is integrated: you only commit on the basis of a complete analysis.
Negotiation, inspection coordination, import management if the vehicle is abroad, customs clearance, type approval, registration, transport, payment security. Collexium acts on your behalf and preserves your confidentiality throughout the process.
We integrate the tax framework from the outset: purchase in personal name or via a legal entity, applicable VAT regime, optimal structuring in coordination with your counsel.
What you get
- —The car you wanted, acquired on the best possible terms
- —Zero operational burden — you decide, we execute
- —A transaction secured, legally and financially
- —An anticipated and optimised tax framework

Advised Sale Mandate
Selling an exceptional vehicle is as complex as acquiring one — and mistakes are just as costly.
We manage the sale end to end. The starting point: an objective analysis of your vehicle's true value and a tailored go-to-market strategy. Which channel? What timing? What price? We answer these questions before putting your vehicle on the market.
Preparation of the documentary file, presentation recommendations, tax framework in coordination with your counsel, market launch, buyer contact management, negotiation, transaction security. If the buyer is international, we manage the export.
Your identity remains confidential if you wish.
What you get
- —The best achievable price in current market conditions
- —A controlled sale, with no overexposure or stigmatisation
- —An advisor whose compensation is aligned with your outcome

Collection Audit
Your collection has been built over the years. But could you say precisely what it is worth, what should be done with it, and how to pass it on?
We carry out a comprehensive review: inventory, updated valuation of each vehicle, analysis of overall coherence. Is there a common thread? Redundancies? Gaps? Vehicles whose value has declined, or conversely arbitrage opportunities to seize?
We map the segments you hold and their dynamics, project value over 3–5 years under multiple scenarios, and open the subject of succession planning in coordination with your notary or solicitor.
What you get
- —A clear and updated view of your automotive estate
- —Concrete recommendations: hold, sell, acquire
- —The initial foundations of succession planning

Collection Oversight
Your collection deserves ongoing attention — without it being your job to orchestrate everything.
We become your single point of contact for everything related to your collection. Personalised market monitoring, alerts on opportunities aligned with your tastes and strategy, semi-annual or annual valuation tracking.
We also coordinate operations: connecting you with specialist workshops suited to each vehicle, monitoring interventions, preventive maintenance scheduling, storage and insurance optimisation. You decide, we steer.
What you get
- —A living collection, monitored and optimised continuously
- —The peace of mind of a single contact who knows every vehicle
- —Time freed for what matters: enjoying it
