4 Opel cars, 4 Bloggers, and lots of credibility discussions

In Germany the car manufacturer Opel has started a blog project to promote the new Opel Astra. Four bloggers are equipped with the new car for four weeks in order to test and review. All the blog posts a sydicated on the Astra blog astra.blogg.de/. Further there is a sweepstake where the users have to send in pictures of the Opel bloggers.
The fact that the bloggers are sponsored with the car and the allowances are paid had kicked off discussions in the blogosphere about credidibility and the sell-out of the bloggs.
