A considered alternative
to simply listing your car.
Selling a Porsche well is rarely about uploading photographs and naming a number. The cars that reach their ceiling are presented as a complete, verifiable story — the right example, documented thoroughly, shown honestly, and offered to the right audience at the right moment.
​
Zuffenhausen Keys exists to build that story, and to carry it through to a result. We work quietly alongside owners and collectors, bringing structure, judgement and the right network to every sale.
1970 911 T
$115,000
IRISH GREEN
Numbers-matching 2.2, original window sticker and Certificate of Authenticity. Originality made the price.
2006 997 Carrera
$47,250
MIDNIGHT BLUE
Two-owner, ~27k-mile 6-speed. Minor damage disclosed openly — transparency that protected the result.
2022 GT3 Touring
$310,250
PTS OSLO BLUE
Paint to Sample, PCCB, carbon buckets, ~1,500 miles. On a modern GT, specification set the number.
HOW WE HELP
Representation, end to end.
01
Valuation guidance
A grounded view of where your car truly sits, built from real sold results — not asking prices.
02
Market positioning
Framing the car for the specific buyers who understand and value it.
03
Presentation
Photography, copy and documentation that earn the first serious bid.
04
Sale strategy
Auction, private sale or curated consignment — the right route, timed deliberately.
05
Buyer vetting
Managed enquiries and qualified buyers, so your time is spent only on the real ones.
06
Negotiation
Protecting your position, and your number, through to a signed agreement.
07
Documentation
A complete, verifiable file assembled before listing — every claim evidenced.
08
Curated consignment
A discreet, fully managed sale from first valuation to final signature.
​
ACROSS EVERY ERA
The levers change with the car.
A 1970 911 T and a 2022 GT3 are valued by almost opposite logic. We lead each car with what its era actually rewards.
AIR-COOLED · PRE-1998
Originality wins
Matching numbers, the correct colour, documented history and honest restoration. Rust-free structure is non-negotiable.
WATER-COOLED DRIVER
Honesty & condition
​Transmission, mileage, condition and a continuous service file — and a seller who addresses known faults head-on.
MODERN GT & LIMITED
Specification rules
PTS colour, carbon buckets, PCCB, the right options and delivery miles. Configuration can move the result by six figures.
“We treat every car as a legacy, not a transaction.”
