Vauxhall has signed an exclusive European sponsorship deal with BuzzFeed that will see the Adam Rocks city car plugged in 15 posts. The campaign, designed by creative agency Carat, will see content sponsored by Vauxhall -- and Opel in the appropriate markets -- simultaneously released in German and English on the site across the continent. The 15 sponsored posts will be marketed towards millennials throughout the year and will mark BuzzFeed's biggest automotive deal ever in Europe.
