Independent · data-led · in the client's interestWe are not a conventional search agency and not a dealer. We bring data, documentation and technical experience together so that buyers and owners can make well-founded decisions about their Porsche 911.
History, specification, condition and documentation have a marked effect on demand, price and how easily a car sells later .
Buyers look more closely and factor gaps in the history, the specification or the documentation into what they are willing to pay. A structured assessment helps you judge the asking price, the costs that may follow and how easily the car will sell later.
From the one-off remote filter through the guided buying decision to a technical assessment and a full search.
The first filter. We check the listing, the paperwork on hand and the market data remotely for plausibility. The aim is to spot unsuitable candidates before you spend time and travel money.
For a car you have already found, when further paperwork, follow-up questions and dealer answers come after the Digital Audit. We guide the remote process through to a buying decision that holds.
We travel to the car and assess it physically. As an independent technical representative of your interests we look specifically for the weak points of that model and document what we find.
For buyers who have not yet found a specific car. We take on the process from the search brief to the vehicle side of the purchase, drawing on our off-market network along the way.
A detailed, model-specific basis for your decision, for example on the 991 Touring, with the technical background and the relevant market data.
For owners who want the history, specification and documentation of their Porsche 911 set out in a structured way, and the current market value range placed in a way they can follow.
We prepare your 911 professionally and place it directly within our network. If you prefer, the marketing is discreet and without a public advertisement.
An end to gut feeling. 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, from Porsche to Aston Martin. Ideal for buying and pricing.
Packages: Single €599/month, Multi €899/month (each plus VAT) or Enterprise, individually priced for all 8 marques. Every package comes with the full range of functions and is cancellable monthly.

Not a conventional car dealer and not a theoretical adviser. As a technician and former workshop manager I combine hands-on technical experience with modern data analysis and a clear specialisation in the Porsche 911.
No stock of our own. For buying advice and sourcing mandates we represent the buying client exclusively.
No seller's commission on buyer mandates. Selling mandates are agreed separately and openly.
Facts beat opinion.
