A single table showing the 12-month valuation history of a vehicle is one of the new features of Glass's Information Services' enhanced Evaluator system.

The PC-based product is designed to give dealers instant access to trade and retail used values, allowing for adjustments for mileage, options, extras and condition. The history-at-a-glance facility is in addition to used values for the current month and the 11 previous months.

The latest version is also capable of generating benefit-in-kind taxation guidelines based on the new carbon dioxide emissions tax regime which goes live in April next year.

Evaluator first went live in April this year, bringing all of Glass's valuation data sets to the PC. Car Values 1993-2001, Car Values 1985-1992, Commercial Vehicle, Motorcycle and Caravan are available on an annual subscription basis.
