Report car lost and claim insurance. Those who having your car will automatically become thief. But you report business crime, it will take forever for processing and probably you will get back nothing at the end. RM115k is quite a high trade in/dealer buying price for a 2005 320i so I would say if it is not a bait, then must be the young salesman give the wrong quote and unable to sell then the company ask him to kawtim by himself.
