"By 2010 market share and profit margin from traditional dealers will decrease resulting in 40 per cent less net profit", according to a new report carried out by consultancy group Accenture. Megadealers and supermarket chains like Tesco and Sainsburys' are set to emerge as dominant forces, providing razor sharp competition to traditional dealer groups, according to the research. Seven in ten of respondents to the Auto 2010 UK survey believed that by "2010 megadealers would be creating tough competition for traditional dealers" and 61 per cent believed that retail chains would provide the next biggest competition. The survey findings on supermarkets is in stark contrast to that shown on mainland Europe. Research carried out by Accenture last year in Europe found no evidence that retail chains would pose a challenge to traditional dealers in the region. It said that one reason is that supermarket chains like Tesco and Sainsbury's already offer insurance and finance at their outlets.
