The engineering office begins.
Klaus Kukuk establishes independent technical appraisal as the foundation of the practice.
Europe · International collector car expertise since 1986
Independent evidence for significant cars across Europe.
KUKUK supports collectors, advisers and institutions with authentication, provenance research, acquisition due diligence, damage assessment and collection governance across borders. Every mandate is independent, scientific and confidential.

The KUKUK method
The vehicle must support the story told about it.
We compare records, provenance and historical references with the material evidence present in the vehicle. The scope follows the decision and the limits of the available evidence.

Evidence from our own work
Cases where evidence changes the decision.
KUKUK case studies show how technical questions are structured, examined and documented.
When a front end must be historically proven.
Does the front with covered headlights genuinely belong to this vehicle’s history?

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 transferring funds.
How records become a usable chain of evidence.
Documents gain value when source, date and relationship to the vehicle remain clear.
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 and reproducible reasoning.
Scientific methods expand.
Material analysis, digital documentation and international research deepen the examination process.
One family, international mandates.
Klaus, Laura and Niclas combine continuity with personal responsibility across borders.
Independent media sources
External perspectives on our work.
