'Glass's Consumer Values' is published by Glass's Information Services Ltd, the market leader in valuation information to the motor trade.
Having developed the idea for Glass's Guide to used vehicle values in 1933, Glass's has built up unrivalled expertise in this field. Its data is the starting point from which almost all used vehicles are bought and sold in the motor industry today.
Glass's takes knowledge from within the trade, researches published prices of used cars and speaks to dealers and other professionals. This information is then used to find the consumer value for most cars between six months and eight years old.
Specialist vehicles in short supply, or other rare models, can't be valued using this service.
