General Motors is running a new advertising campaign in the US to lure car and truck buyers who wouldn't usually consider the firm's various brands into showrooms, Reuters reported. GM will reportedly launch the print campaign next week to convince the 40% of US vehicle buyers who shun its models that GM vehicles now have world-class quality and it will follow with other ads aimed at improving GM's overall image beyond the pile of incentive deals it regularly dangles in front of buyers, the news agency said.
