Ok, looks like i'll have to elaborate a bit more then, neighbour was having a party and there was loads of people over, I'm convinced it's someone he knows that was leaving, I have been through twice and he denies any knowledge of it, he said he would ask everyone that was there, but that didn't get me anywhere, i looked out the window earlier and i'm sure the car i saw was there, can't have been there long as I was in the house for about 5 mins and it wasn't there when i came in, anyway by the time i'd gone to do something in the kitchen for two mins and came back it had gone AGAIN!!!!!
