Technical condition and commercial judgement

Why "Porsche Approved" alone is not enough

A warranty can cover defined technical defects. We make the commercial risks visible. Even a technically good 911 can be commercially unattractive if the price, the specification or the timing in the market are wrong.

Porsche protects the engineering

Engine, gearbox, components.

We assess the commercial context

A realistic market price, resale potential and the timing of the investment.

Travel & location +

Travel is calculated from our base (Fehmarn) at €0.59/km. It is added to the Technical Due Diligence fee of from €790 incl. VAT.

Retainer & success fee for the sourcing mandate +

The sourcing mandate starts with a retainer of €1,500 incl. VAT, which is offset against the purchase. On completion a success fee of 3.5 % of the purchase price plus VAT is added (corresponding to 4.17 % incl. VAT). Included are the Digital Audit and the Purchase Advisory for every serious candidate, the conduct of negotiations, support through the vehicle side of the purchase and strategic investment advice.

Legal notes +

All prices for private clients include statutory VAT. Trade prices on request. A viewing does not replace the German statutory roadworthiness test (Hauptuntersuchung) under §29 StVZO. A legal review of the contract or legal advice is not part of the services. The exact scope follows from the particular offer. Travel is calculated from our base on Fehmarn at €0.59/km. Our Terms and Conditions with the description of services and the right of withdrawal apply.

Our market monitoring system has grown into a platform of its own, MarqueScope . It watches the market for 8 premium marques in over 40 markets and shows in seconds what a team used to need hours for. Every package contains the full range of functions; the only difference is how many marques are unlocked. Cancellable monthly.

Why it pays for itself

The calculation from marquescope.de: an average vehicle price of €180,000 and an estimated margin of €12,000 per car. A single bad purchase avoided therefore saves you €12,000. MarqueScope Multi (€899/month) amounts to 0.50 % measured against the vehicle price. If just one deal per quarter turns out better by that margin, the benefit of €48,000 a year is 4.4 times the annual cost of €10,788, a net ROI of around 345 %. In short: a single better deal can pay for the annual subscription. The worked example rests on an estimated margin and is not a guaranteed outcome. MarqueScope does not replace your experience. It makes it demonstrable.

Our market monitoring system has since grown into an intelligence platform of its own for dealers: Discover MarqueScope →
