I think you should go hard and get the information out there (if you have'nt already done so that is) Nobody likes car thieves, put notices in the local newspaper and nearest regional centre newspaper, make some copies and place them on notice boards, talk to all the neighbours in your area, if you can post up a reward for info leading to the recovery do so, cruise around with a mate check out the local car hangouts see if you can spot it and keep in mind they could have altered it or sold it to someone who does'nt even know its stolen. Good luck in the search.
