This week's picture comes courtesy of PHer '
' who took this photo at the recent Goodwood Festival of Speed.
We think it really captures the speed and drama of these old rally cars as they scrabble for grip through the forest, sliding sideways inches from the trees.
If you've taken any great pictures which you think would make for a worthy Pic of the Week then please email them to us and you too could be featured on the front page of PistonHeads.
