The engineering office begins.
Klaus Kukuk establishes independent technical appraisal as the foundation of the practice.
United States · independent collector car expertise since 1986
Independent evidence for collector car decisions in the United States.
KUKUK supports collectors, family offices, advisers and institutions with scientific authentication, acquisition due diligence, provenance review, estate intake and collection governance. We connect European vehicle knowledge with the practical questions that arise in United States ownership and transactions.

A family engineering office
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.
Independent since 1986IHK sworn expertiseScientific methodsInternational mandates
A coordinated international mandate
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.

Evidence from our own work
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 ↗Knowledge for decisions
Methods, limits and practical guidance.
Our articles explain what an examination can establish, where uncertainty remains and which evidence should be secured first.
What if the vehicle is not authentic?
The evidence that separates identity, originality and historical correctness.
Why enthusiasm is not an inspection method.
A practical view of risk before bidding, signing or wiring funds.
How records become a usable chain of evidence.
Source, date and relationship to the vehicle make records useful across borders.
KUKUK heritage
Independent responsibility since 1986.
Four decades of engineering work shape how we examine, document and communicate evidence today.
Evidence for insurers and courts.
Damage, causation, repair and value questions require transparent reasoning.
Scientific methods expand.
Material analysis, digital documentation and international research deepen the examination process.
One family, international mandates.
Klaus, Laura and Niclas combine European vehicle knowledge with personal responsibility.
