Independent engineering office since 1986.
The reference for automotive truth.
KUKUK Ingenieure combines engineering, materials analysis and collector car expertise to make authenticity, condition, value and history measurable.
Expertise that has to stand up in court.
Independent consulting and engineering with a forensic methodology. Every mandate is led by automotive engineers, supported by laboratories, professors and model specialists when the question requires it.
Court contexts in Germany, Italy, the Netherlands, the United Kingdom and the United States.
Germany’s first publicly appointed and sworn expert for classic cars through the Cologne Chamber of Commerce.
Mandates for leading manufacturers, specialist dealers and international auction houses. Selected professional contexts include Maserati Classiche and RM Sotheby’s.
Where does evidence protect the decision?
The scope follows the vehicle, the records and the financial or historical question at stake.
KUKUK Authentication Dossier
Materials, stampings, assemblies, documents and provenance examined as one body of evidence.
↗ 02AcquisitionKUKUK Acquisition Due Diligence

European vehicle knowledge with personal responsibility.
Klaus, Laura and Niclas Kukuk combine expert appraisal, engineering, research and international collector car work. United States mandates are coordinated personally and documented for the agreed decision, recipients and jurisdiction.
One evidence file across locations and advisers.
We review records, define open questions and coordinate the physical examination where the vehicle is located. Findings are written for the agreed decision and recipients, with limits stated clearly.

Cases where evidence changes the decision.
These cases show how KUKUK structures authentication, acquisition and damage questions.

When a configuration must be supported by historical evidence.
Does the covered headlight front genuinely belong to the history of this vehicle?
Open case study ↗Why unrestored substance requires a different reading.
A Mercedes Benz 300 SL in Paris demonstrates the technical language of original material.
Open case study ↗
What must be secured when damage appears after transport.
Condition, timing, causation and responsibility need a coherent evidence record.
Open case study ↗
Four specialist pages for the question at hand.
Choose the subject that matches the collector vehicle, available evidence and transaction or ownership decision.
Ultrasound, borescope or CT?
What each method can show and where its limits lie.
What can a frame inspection establish?
Identity, material, manufacturing evidence, repairs and uncertainty.
KAR™ and the KUKUK Signature™ layers
How evidence, material and released digital information are connected across borders.
What should a pre purchase inspection cover?
Structure, material, identity, records, restoration and risk.
Where we come from.
From technical appraisal work to forensic materials analysis, research and digital documentation: these milestones show how our independent engineering practice has developed since 1982.
Expert appraisal work begins.
The technical view of damage, causation and value becomes the foundation of KUKUK.
The engineering office is founded.
Independent expert reports for demanding vehicles become the core of the family practice.
OES materials analysis.
Material, period and substance become measurable rather than merely asserted.
Fry and Adler etching.
Stampings, relief markings and concealed digits are examined forensically.
X ray examination.
Hidden structures become visible without unnecessarily opening historic material.
Three dimensional capture and photogrammetry.
Geometry, archival material and the physical vehicle become directly comparable.
Sworn expertise for classic cars.
Germany’s first expert publicly appointed and sworn by an IHK specifically for classic cars.
3D and CT analysis.
CT supported examination strengthens questions concerning hidden components and identity.
Research and cooperation.
Academic collaboration advances the next stage of scientific vehicle verification.
A family practice with a system.
Experience, research and digital documentation combine to create robust vehicle evidence.
What decision needs to be protected?
Share the vehicle, location, records and timing. We normally respond on the same business day and propose a clear review or examination scope. A protected upload can be arranged.
