The cutback is part of moves aimed at promoting a steady growth in business via better quality sales.
Company chairman Jonathan Browning said the plan for sustained expansion and more closely managed residual values called for a reduction in the number of vehicles supplied to short-cycle outlets.
Browning, who is also sales and marketing vice president of General Motors Europe, said: ‘We are remixing our business. The plan is for us to remain as the leading supplier to the fleet market by gaining 25,000 sales through other channels. We’re carrying out a lot of fine-tuning to our operations.
‘Vauxhall is still performing strongly in fleet and the Chevrolet brand is developing well as it adds new models to the GM range of products. We’re undergoing a lot of change and will pay more attention to investigating new opportunities in the sub segments as we optimise our mix of products.’
