There’s no doubting the whirlwind success of the Insignia since it was launched to dealers in January 2009. After collecting the coveted European Car of the Year gong, the Insignia’s been a near-constant top seller in the UK’s D-, or mid-size car sector, achieving over 36,000 sales in its first full year, and is now heading for its best year ever (29,987 YTD, July ’11), outselling notable challengers like the BMW 3-series and Ford Mondeo.
