I'd think that if it is out and about, the plates will have been changed by now. Friends lost their Golf MK5 and newish A6 Avant last year same way. The Golf seems to have turned up 3 months later judging by what became a stream of parking tickets that started to appear through the letter box, followed by heavy threats of action! They contacted the local police to stop that as the insurance company now owned that car! (both cars had been used to block in taxis and steal their cash after they had been taken from the house, then the Golf had been parked up and abandoned in Edinburgh which was only 10 miles from where it was taken!). A week ago the A6 turned up in Lanarkshire, this car, with different reg plates had been reported as being left abandoned for a long time, so the police got involved and checked its VIN, now they need some fingerprints and asked if the guy wanted to see his car, which he does not now but he would like to know what the mileage currently is - don't think the police are willing to hand over that info as it would reveal just how much use this car has had after it has been stolen as so put them in poor light?
