Thanks for that, I do know who it is/was now, they were "caught" on just about every camera, the moving one as they came down the main road, a fixed one as they turned into the road and another fixed one as they hit the car.
I'd also forgotten (despite it being me that fitted them) that my cars have cameras in them (it's one of the conditions of insurance as we drive blue light vehicles) and they were recorded on that as well, so chances of saying "it wasn't me".....quite slim I would have thought.
The police have said that they can't do anything yet as they have 24hrs (a reasonable time) to report the accident before it becomes more serious, so we'll see what happens tomorrow.
As a separate note, the car isn't too bad, ripple on the wing and scuff on the bumper, was thinking about getting rid of it the last week and this has kind of pushed me, so if anyone wants to buy a really cheap 02 Chrysler Grand Voyager Limited, seven seater 3.3 with an LPG conversion and a series three facelift (so it looks newer, with a private plate you'd never know it wasn't an 07) then let me know. Had a £3k engine rebuild at BEC 7k miles ago, if I get back £3500 I'll even have it cleaned
