Honest substance
I do not sell dreams. I test them. If a car looks glorious but is technically questionable, I say so plainly and directly.

About 911FinderWhy a former workshop manager now produces Porsche 911 market analysis, to make buying decisions more transparent, safer and easier to follow.

What began as a child's fascination became a profession, a passion and finally the idea behind 911Finder. Over many years I have worked on countless Porsche models, and above all on the different 911 generations, from the classic Carrera to the uncompromising GT3.
As a technician and former workshop manager I learned every day what really matters when it comes to precision, engineering and authenticity.
"I had to sell my first 911 to buy a house. That taught me something: no other car brings engineering, history and character together so uncompromisingly."

911Finder grew out of that experience. I help people find the right 911 for them: not just any listing, but a car that fits technically, historically and emotionally.
For that I use a market monitoring systemI developed myself. It records the publicly offered cars of more than 5,500 active dealers in over 40 markets every day and analyses price trends, specification features and wider movements from them. I see more than patterns in data: I see the detail behind the figures, such as thermal weaknesses, cylinder liner damage or typical fault patterns.
I do not sell dreams. I test them. If a car looks glorious but is technically questionable, I say so plainly and directly.
Plenty of people have had enough of sales poetry. I give you clarity through market data, days-on-market analysis and technical facts.
For buying advice, assessments and sourcing mandates I represent the buying client exclusively: I work on a fee basis and accept no commission from sellers. Selling mandates are separate services, always identified as such, where I represent the owner.
Then I would be glad to meet you.
