ClickZ reports General Motors will launch a print and online advertising campaign in the US to create awareness of the GM Certified Used Vehicles. The ads feature the tagline "No Worries" and use a series of images to explain that when you buy a used car there are a lot of things you no longer have to worry about.

The agency behind the campaign is IPG's Mullen. Online ads will appear, among the others on Autotrader, Aol Autos and Cars.com. Search engine advertising will also be part of the effort with keywords bought on Google and MSN Search.
