Independent counsel in a market that is not

Collexium Advisory was born from an observation: in the exceptional automobile market, there was no independent advisor working exclusively in the interest of the buyer, the seller, or the collector. Never all three at once.

Why Collexium exists

The collector car market operates on long-standing relationships, established reputations and practices rarely questioned. Traditional intermediaries — dealers, auction houses, brokers — play a useful role. But their fee model creates a structural bias: they serve whoever pays them first, and that is not always you.

Collexium Advisory was designed to offer an alternative. Counsel whose sole mission is to protect and serve the interests of its client — whether buying, selling, or managing a collection. Not a dealer who advises on the side. An advisor, exclusively.

Our principles

01

Independence

We hold no inventory, no cross-selling mandates, no commercial partnerships with sellers or auction houses. When we recommend a vehicle, a workshop or a sales channel, it is because it is the best option for you — not for our margin.

02

Transparency

Our fee model is disclosed clearly from the first conversation. You know exactly what you are paying, why, and what it covers. No hidden commission, no concealed margin in a transaction.

03

Rigour

Every recommendation is grounded in verified market data — not intuition or hearsay. Our reports are designed to enable you to decide with full knowledge — and to withstand a second opinion.

04

Commitment

A single point of contact who knows your collection, your objectives and your constraints. We do not delegate your file. The relationship is direct, continuous, and built over time.

05

Excellence

When we recommend a workshop, a transporter, a sales channel or any other service provider, it is because we have identified the best for the precise task at hand. We apply to the selection of our partners the same standard our clients expect from us.

Financial methodologies applied to a market that lacks them

The collector car market is analysed, when it is at all, by model. That is insufficient. Two examples of the same model can have a value that varies by a factor of three depending on their specifications, provenance and history. An average price per model says nothing — or worse, it misleads.

We have built an analytical methodology inspired by practices in financial markets and alternative asset management, adapted to the specificities of the exceptional automobile market.

Reading the market as it is

Our analyses cross-reference public sales and active inventory to avoid any single-channel reading. They are produced by geographic micro-market — Europe, United Kingdom, United States, Middle East — in order to isolate tax and currency biases. Prices are consolidated on a total buyer cost basis, with same-day currency conversion where applicable. Comparisons are not made by model, but on a like-for-like specification basis: variant, options, configuration. It is at this level of granularity that true value dynamics emerge.

Understanding what performs — and why

We do not simply compile results. We reprocess them to identify the true drivers of performance over a given period. Specifications, provenance, competition history: these factors can multiply the value of a specific car by two, by three, sometimes more. These are the signals our analyses isolate and quantify.

Indicators designed for decision-making

Each analysis produces defensible and actionable indicators:

Value: ranges based on median and dispersion, never a single price

Trend: observation windows adapted to the liquidity of each segment

Risk: volatility, drawdowns, correction history

Liquidity: volumes, unsold rates, depth of supply, signals of tension or easing

Data quality: identification of outliers, atypical lots, regime breaks

In practice: seeing what the market doesn't show

An investor has €300K. The natural reflex points toward a Mercedes-Benz SLR McLaren — an iconic model, accessible within this price range. Over five years, the SLR shows a gain of +1.4%, with no significant variation across specifications. A virtual standstill.

With the same budget, few would spontaneously think of the Ferrari Testarossa. And for good reason: the model averages around €160K — well short of the budget. But this is precisely where model-level analysis reaches its limits.

When you drill down by specification, the picture changes. Red Testarossas — the most common configuration — have gained approximately +45% over the same period. A solid result. But examples in non-red colours, which now trade above €250K, show a performance in the region of +75%.

Two cars at the same entry price. On one side, +1.4%. On the other, +75%. And a signal entirely invisible in a conventional reading of the market.

For the sake of simplicity, we have isolated only one factor here: colour. In reality, our analyses cross-reference all the variables that structure an example's value — colour, options, mileage, history. It is at this granularity that true performance asymmetries emerge.

For a client whose objective is return, our role is not to confirm an intuition — it is to confront it with data, and to surface opportunities the market is underpricing.

This level of rigour does not exist in this market. That is precisely why we built it.

Transparent fees, aligned with your interests

Our model rests on a simple principle: you should always know how and why we are compensated. Here is how it works across our services.

01

Advisory and analysis

Fixed fees

Advisory engagements (Decision Report, Collection Audit, Investment Strategy) are charged as fixed fees, agreed in advance. You know the amount before committing. Our recommendation depends on no transaction.

02

Acquisition and disposal

Fixed fees or fixed fees + success fee

Execution engagements (Bespoke Execution, Acquisition, Sale Mandate, Disposal) are charged as fixed fees. For sale mandates, a success fee indexed to the price achieved may be added — it aligns our interests with your outcome.

03

Oversight and management

Annual retainer

Recurring engagements (Collection Oversight, Portfolio Management) are charged as a fixed annual retainer, defined according to the size and complexity of your collection.

04

Operational coordination

Disclosed coordination fees

When we coordinate third-party services (restoration, transport, storage), our coordination fees are clearly identified: a supervision flat fee or a disclosed percentage depending on the nature of the work. For insurance and financing, we act as an introducer — at no additional cost to you.

In every case, our fees are disclosed before any engagement begins. There is no grey area.

How we work

01

Listen

Every engagement begins with an in-depth conversation. We understand your objective, your constraints, your sensibility, your history with the automobile. No standardised questionnaire — a conversation.

02

Analyse

We deploy our market data, our network and our technical expertise to produce a factual and complete analysis. Every element is documented, every recommendation is substantiated.

03

Recommend

We present our conclusions with clarity: the options, the risks, the opportunities, and our recommendation. The decision is yours — our role is to give you every element to make it with confidence.

04

Execute

If you entrust us with execution, we coordinate every step with the same rigour. You are informed at every milestone. Nothing happens without your approval.

Frequently asked questions

Who is behind Collexium

Alexandre Foughali

Founder & President

A tax lawyer by training, Alexandre practised in law firms then in international tax departments. He subsequently studied art history to enter the auction world, with a clear objective from the outset: to ultimately join the field he is passionate about, the collector car market. There he observed from the inside a market where passion often prevails over reason, sometimes to the detriment of those who invest in it.

Enthusiasts who discover after taking delivery defects that nobody had mentioned. Six-figure decisions made on intuition rather than analysis. Collectors want to look ahead — but they have neither the tools nor the time to do so rigorously. They rely on market professionals, who assert a vision without ever documenting it. And for good reason: a dealer or auction house has no interest in analysing what a vehicle will be worth in five years — they will have cleared their inventory long before.

Collexium Advisory was born from this conviction: people who devote considerable sums to exceptional automobiles deserve the same analytical rigour as for any other asset class. The discipline of tax law — where every decision must be justified and defensible — applied to a world that could lack it.

The automobile is also a personal story. Mine begins at Spa-Francorchamps in 2000, aged nine, the day Mika Häkkinen overtook Michael Schumacher three abreast between Kemmel and Les Combes — probably one of the most audacious overtakes in Formula 1 history. On leaving the circuit, I was nearly run over by the very same Häkkinen, who had just swapped his victorious MP4-15 for the wheel of a rather more modest Mercedes E-Class. He came even closer to me than Ricardo Zonta's front right wheel had during that legendary overtake an hour earlier. Not one to hold a grudge, it didn't stop me making him my favourite driver of that era.
