With justifiable pride GM's UK arm trumpeted its success in April: 'Vauxhall storms to the top of the charts!' headlined its news release. In that month it seized 14.9 per cent of the British new-car market, against 13.8 per cent for Ford, the only other company with a double-digit share of UK auto sales. Vauxhall's market share was up from 11.5 per cent in the same month in 2004, while Ford's was down from 15.5 per cent. This was good going for Vauxhall in a month that was down 4.0 per cent from last year's April, writes Karl Ludvigsen.
