The six deliberative workshops, each with 8-10 participants, were conducted in six major UK cities/towns, each
lasting two and a half hours in length. In all cases, group discussions were recorded and transcribed in full for
later analysis. In return for taking part in the project, each survey participant received a cash reward of £50 or
£60 (depending on venue). Using a discussion guide, which included extensive visual stimuli, the groups were
invited to discuss their attitudes regarding: the most important factors during car purchase; useful information for
car buyers; metrics included on the current label and their presentation; alternative ways to present information;
the demand for comparative vehicle data; how best to present information for new plug-in vehicles; and the
potential for using web-based tools for vehicle comparison
