About Us

Glass's was founded in 1933 by William Glass and the first Guide to Car Values was published in July of that year. Since that time the company has expanded into Commercial Vehicle, Motorcycle and Caravan values, supplying data in printed, electronic and web formats.

In 2008 Glass's celebrates its 75th Anniversary - no-one has been valuing vehicles longer than we have. We are the market leader - our guides and valuations are widely used throughout the entire automotive industry - from car dealers (where we estimate that more than 90% buy Glass's Guide to Car Values), to insurance assessors, vehicle fleet and finance houses and increasingly by private consumers who wish to ensure that they are getting an accurate part-exchange valuation for their car, or to check that the asking price of a vehicle that they are interested in buying is fair and reflects its market value.


Today Glass's offers products and solutions that are invaluable at every stage of a vehicle's lifecycle. From key valuation, technical and fleet management data to estimating, bodyshop and dealer management systems and web-based services, Glass's has information that the industry relies on.

In 2000 Glass's merged with Eurotax, forming Europe's leading supplier of automotive business intelligence across 28 countries. The merger created a group with unrivalled resources and knowledge and is paving the way for many exciting future developments.
