I like that a few of the F1 drivers are on Twitter 642-453, but it looks like Di Grassi has biten off more than he can chew. He ran a competition to design a background for his Twitter 642-481, and said 1st place wins signed gloves and 2nd and 3rd win a signed visor, but 4 months on and the winners haven’t received their prizes and are losing their faith in Lucas 642-533. So much so it looks like they don’t even want to support him any more it’s such a shame.
