Step 2 · How to work with it

Three situations where the compendium counts

From the first listing to the price negotiation: each edition is structured so that you can start at the right place.

Before the trip

Judging an offer

Part 1, the technical deep-dive, describes the model's weak points, engine codes and specification details. From it follow the questions for the seller before you invest time and travel.

  • Weak points by assembly group
  • Engine codes and specification details
  • Service intervals and running costs
At the car

Preparing the viewing

The appendix provides worksheets, checklists and assessment forms for the viewing, the PPI, the documents and the test drive. Print, bring along, tick off.

  • Checklists for viewing, PPI, documents and test drive
  • Assessment forms for the specific car
  • Inspection record as the basis for negotiating the price
Before negotiating

Placing the price

The investor dossier shows price development, the relationship between price and mileage, time to sell and scenarios for the coming years. So you know what a premium for specification or history is worth.

  • Market price development and price-mileage correlation
  • Time to sell and liquidity
  • Return, scenarios and risks
Step 3 · Check the quality

Read original pages before you order

The reading sample contains unchanged original pages from the edition on the 997.1 Carrera, S, 4 and 4S: engineering, buying advice and investor dossier. Tables, info boxes and chapter numbers appear exactly as they do in the book. Free of charge, no details required.

Part 1 · Engineering: damage pattern and fact check
Part 1 · Engineering: damage pattern and fact check
Part 5 · Investor dossier: the adjusted calculation

Who is behind it

Author and method

Thomas Ottenstroer is a technician, former workshop manager and market analyst. He founded 911FINDER, the buying advisory and brokerage for the Porsche 911, and developed MarqueScope, the market data platform from which the market sections of the compendiums are drawn.

Each edition states its data date on the product card and in the book. The market sections are based on documented listings and sales from the continuous monitoring of the 911 market; every analysis in the book names its data basis. The engineering sections come from workshop practice, damage patterns and inspection records.
