Social networkers are winning all kinds of rides. Ford's might give away an Explorer on Facebook and Citroën UK just launched a game called DS3 StreetSeekers that will be gift three of its new superminis. During each five-day round of the treasure hunt, go to the marque's fan page and a little bit of snooping around the Google Street View map will yield a piece of a DS3. Every day there's a new clue about where the another piece can be found, and when someone collects four pieces they get the clue about where to find the complete car. Track that one down, and you could win it.

There are three rounds to the competition and the first one ended last week. The second round runs from August 17-21, and the third from September 7-11. Happy hunting...
