Auto Trader, the motoring website and magazine, is hoping to take a larger stake in the new and used car marketing market with its biggest brand investment in 30 years.

The relaunch will include a new logo and redesigned website and magazine. It will be backed by a multi-million pound marketing campaign, encompassing TV, radio, online, forecourts and retail. The strapline will be 'The World of Cars Made Easy', and it begins on February 28.

Auto Trader is targeting four key motoring audiences: 25-34 year old females, 25-44 year old male motoring enthusiasts, 45 year old and over with families and 45-65 year old high earners.

The magazine will include an easy-to-use contents guide and improved editorial content, including new car reviews.
