Many thanks to all of you who have made comment.
Just to bring you up to date, I have seen the car and there is no real damage except to the stero unit that the w******* have tried to remove, some slight damage to one alloy and cut tyre wall, other than that nothing visible, dont know what state the engine and suspension is in after they have driven it.
Other main problem is that there is a key in some scrotebags possesion and the insurance company need to understand that they cannot just change the locks.
Car minus child seat, pushchair and about £300 worth of cd,s.
I suppose it could have been a lot worse.
Again many thanks to all of you that passed messages of support.
