Ai maybe, I live in a cul-de-sac off of a main road, not the sort of place you would just happen to pass by in general. My neighbour who told me about the "veiwing" said the car came up the road, slowed at my gaff, pulled past the drive, had a real good look, span the car around, same again on the return... I was hoping I would get a "yeah it was me having a cheeky sneek peak" not knowing who kinda makes thing ominous.
Oh, a bit strange that they happen to find it in a cul-de-sac then. If it was passing in a street I would probably not worry so much. Best to keep an eye on it like you have been and keep the torque wrench nearby
