The latest news, explanatory films, interviews and publications on the subject of cars!

Concorso d’Eleganza VDE 2023

The classic form of the event ended in 1952. In the mid-1980s it was revived, and today it is run by German manufacturer BMW. 

A magnificent place to work 

The spectrum ranged from rarities from the 1920s, a time when aesthetics started influencing car design in addition to functional considerations, to the spectacularly designed hypercars from the future. As part of the jury, we spend months before the event meticulously researching each car and documenting our findings. Obviously, we focus on the groups or cars assigned to us and exchange information among our jury group.

The ICE - St. Moritz 2023

The ICE St.Moritz is a very different event, a refreshing concours. A completely magical environment where drivers, collectors, and just plain car enthusiasts enjoy a late winter day in the sunshine, surrounded by the landscape and atmosphere that only St.Moritz, at the top of the world, is able to offer.

Visit RETRO CLASSICS®, the world's largest and most beautiful meeting place for lovers of automotive legends from days long gone as well as classic car gems of tomorrow.

  • Comparative studies
  • Verification of year of manufacture and manufacturer period
  • Cooperation with sworn material analysts, chemical laboratories and universities

Ms Kukuk was supposed to evaluate a car for me to buy in Cologne. She did it perfectly within 24 hours. I have rarely experienced such a good service and the expertise was meaningful and understandable. I can only recommend the company Kukuk to others with the best of consciences.

Kukuk knows what, investigates, researches, everything with the help of the most modern (and partly to be developed!) technology...and puts it all into an understandable and comprehensible form. You can't get it for €fifty...but do we expect top gastronomy for that? Besides, his expert opinions are reliable....for insurance companies, in court. Do you know anyone better?

Hourly wage survey

You are also in the classic car business and we would very much appreciate your participation in our survey!

There is no representative survey of hourly rates, especially in the area of classic and special vehicles. The DEKRA survey on hourly rates does not meet the specific requirements of classic cars. We have therefore decided to conduct an annual survey of representative classic car specialist businesses.
