Hope you were ok and there wasn't too much damage, the recovery people seemed to be towing you out when I passed so didn't stop as I was late (as I perpectually am).
Erm, I was passing at speed I'm afraid so best guess was that it was a silvery blue aero 8 (I think that's the model). It didn't look too bad and was being towed backwards on its wheels so fingers crossed.
