Guide: what is important about a car value appraisal?

Guide: What is important about a car value appraisal? Ever wondered what's behind the magic of a car appraisal? Let's demystify it! A value appraisal is a meticulous dive into the heart and soul of your vehicle, where history meets mechanics. We don't just look at the car; we look through it. From the engine's purr to the story behind each scratch, we assess, evaluate, and translate metal into money. Why? Because every car has a tale, and every tale has its worth.

Journey Interview

JOURNEY Magazine - Interview: The great freedom

Both are on four wheels - that's all they have in common for now. Vehicle technology engineer Laura Kukuk is in demand worldwide as an expert on classic cars and is convinced of their sustainability. Daniel Zellinger from FlixBus swears by modern buses as a more environmentally friendly alternative to cars. Where is the journey going? To the same destination, actually. A conversation about the mobility of tomorrow.

Overview of our natural science services

We place the greatest value on: Professional competence, quality and transparency

Material analysis by means of spectrometry

  • Spectrometry, as a forensic scientific method of checking the originality and authenticity of a vehicle, has been used in our engineering office since 1986.
  • Dating of metallic materials
  • Non-invasive, mobile and can be used at any time
  • Comparative studies
  • Verification of year of manufacture and manufacturer period
  • Cooperation with sworn material analysts, chemical laboratories and universities

Material thickness measurement

  • Ultrasound for coating thickness measurement of paint and metal
  • by means of eddy current, magnetic inductive or ultrasound method
  • Comparison of the values with the technical drawings of the vehicle manufacturer
  • Sheet metal thickness measurement for originality testing and safety
  • for determining the initial paint, filler and paint build-up and the quality of sheet metal, fibreglass and carbon surfaces

Endoscopy + weld seam testing

  • Visual and assembly-free inspection of individual components (cylinders and cavities in the vehicle frame) e.g. for corrosion and rust detection
  • Inspection of the cylinder to detect engine damage
  • Assessment of the condition of individual cavities
  • Non-destructive materials testing
  • Visual inspection: welding procedure, quality, positioning

3D scan / model / X-ray

  • 3D scan for damage and repair assessment
  • Spare parts production
  • Supporting the restoration e.g. by making a tapping model
  • Comparative investigation and detailed assessment
  • Evaluation of repair and restoration
  • Material compaction recognisable
  • Embossing marking examination
  • Material failure e.g. cracks and blowholes in the material core

Magneto Optical Method

  • Matching Number Verification
  • Revealing hidden digits, double strokes, grinding marks
  • For almost 7 years we have been able to NON-INVASIVELY examine embossed markings on vehicles and in 95 % of the cases we have a meaningful result.

History research

  • Certificate and data card procurement - Manufacturer
  • Contacting historians, type referees and clubs

Oil analysis

  • Determine wear condition
  • Early problem detection before damage occurs
  • Estimation of life expectancy
  • Conclusions about vehicle condition
  • % wear determination
