looks like the car is not sold yet or sold illegally to someone who does not know the proper procedures in buying a car. if we can send message to most BMW car repair shop, these mechanics might be able to help to locate the car faster, just a thought.
Lesson learn: never let someone have your car away for selling, if we need to let someone sell it for us, give them the car pictures/copy of JPJ card only.
Or use the classified/motor trader ads or online ads like BMW clubs, cari.com etc.
I suppose in this case Used Car dealer is safer and less hassle though we might lose some value compare to direct selling.
