The reorganisation includes the formation of a new information management team under the leadership of Ann Wood, a specialist in contact centre management with 20 years' experience in the motor trade.
Her team is responsible for a number of Vauxhall initiatives, including the 48-hour test drive programme aimed at company car drivers changing vehicles.
The test drive fleet currently numbers more than 500 cars across the Vauxhall range. From mid-July onwards, the new Vectra range will be added to the fleet in a bid to target as many fleets and user-choosers as possible.
The information management team also handles enquiries on alternatively-fuelled vehicles and general enquiries, such as carbon dioxide emission levels relating to the new company car tax system or changes introduced in the Budget.
A new customer development team has been set up under team leader Linda Colley, providing support to Vauxhall's 32 field-based fleet sales managers and their fleet customers.
They help direct fleet contact and assist the field team in their work with industry. The final part of the restructuring involves the creation of the role of new business development team leader, awarded to Derren Martin.
Martin, who has had a number of fleet and retail roles, is working on a new business strategy for Vauxhall Fleet.
Teams under the new regime will report to fleet sales support manager Colin Goodchild, who manages the 40-strong nerve centre within Griffin House.
He said: 'The new structure is aimed at making us more proactive and customer-focused.'
