Quick update, car has been found in the next village a couple of miles away, undamaged and just locked up at the side of the road. So it would seem not professional car theives as first thought, but burglars who took it cos it was there. Unfortunately the scum still have a keyfob though, so it's still going to be an expensive job to get all the locks changed and coded in. Going to have to do the same with his son's corsa as they took a set of keys for that too, although they didn't touch that car.
