Our business has been built on the foundations of thought leadership, ever since the early days when William Glass and Hans Schwacke, both pioneers in their own rights, founded Glass’s and Schwacke.  Schwacke expanded in Europe under the banner of Eurotax and in December 2000, Eurotax and Glass’s merged to create EurotaxGlass’s International AG.

Eurotax and Glass's Information Services merged in December 2000 to create EurotaxGlass's International AG. Today we lead the field in providing automotive data, software solutions and business services to the automotive sector. We provide a secure point of reference in a complex market with our pan-European knowledge combined with consistent and comparable international data and innovative solutions

1933 William Glass publishes “Glass's Guide to Car Values” for the first time. This publication quickly becomes the “Bible” of the UK motor trade.

Hanns W. Schwacke applies the same simple and successful idea in Germany. His price list for used cars becomes the first of its kind in continental Europe. Parallel to this, Glass's enters the Australian market.

Schwacke expands the business in Europe. Under the international brand “Eurotax”, subsidiaries are established in Belgium, the Netherlands, Italy, Austria and Switzerland, providing local car dealers and insurers with universally valid vehicle residual values. Glass's launches used valuation guides for commercial vehicles and motorcycles in the UK.

The first calculation system for repair costs offers the retail trade detailed information on parts prices and labour costs for all makes and models. Even minor damage now can be taken into account in used car trade-ins.

The information revolution takes off – the PC transforms the workplace. Eurotax and Glass's recognise that new technology lends itself to the provision of even more comprehensive information and to the application of more demanding calculation methods. The first Autowert workplace software is installed. Autowert becomes the standard for over 15,000 dealers and over 50,000 users across Europe. Glass's introduces the PC version of the Glass'sGuide and acquires Editions Professionelles Glass SARL (EPG), France.

The Eurotax and Glass's data becomes industry standard and is used by European governments to drive national registration systems. New, innovative solutions and systems for the industry are created to support mechanical and accident repairs, forecasts of future residual values and bodywork construction management.

Eurotax and Glass's merge to create the European market leader in automotive business intelligence.

EurotaxGlass’s is acquired by Candover from HM Capital Partners LLC (formerly Hicks, Muse, Tate and Furst Incorporated), for an enterprise value of €480 million.


EurotaxGlass’s launches its Global Service Division to drive international growth.  The fast-growing EurotaxGlass’s Market Intelligence Unit which provides bespoke reports and intelligence services to global vehicle manufacturers, fleet and finance companies becomes part of the new division.


EurotaxGlass’s starts developing new statistical models to meet the demands of the 21st Century.  It acquires Grey Hen, a Finnish company with sophisticated stock profiling and business intelligence tools, which it renames Autovista.

Arle Capital Partners is established in April 2011 following a management buyout from Candover Partners. 


We rebranded back to Glass’s in the UK and changed the face of valuations by redefining the way valuations are developed.
