Here is a really great bit of work from glue London, one of Isobar's agencies:
www.thegreatcarcoverup.com which is running until 4th October, gives consumers the chance to win one of three mystery cars - a stunning convertible worth tens of thousands of pounds, a guaranteed head turner or a complete dud. But which is which? The website provides footage of the three cars that have their identities concealed. They have been filmed in a secret
Users are able to view the three mystery cars by looking at three different camera angles and they are also able to view Mike the security guard keeping an eye over the cars. The website offers consumers a free bonus entry into the prize draw if they send on the competition details to their friends, as well as a car popularity graph so that they can see which car is receiving the most votes."
