Hi,
I have shipped my car from KL to Miri before. I used Subali Pack. They provided extremely good door-to-door service with excellent skills. My car was placed in a container to avoid salty sea water and sea wind. It is also being insured throughout the whole journey. They have professional workers to deliver the car in safely manner and the customs clearance was also well taken care off. They will keep close contact with you and inform you when your car has arrived  and they will delivered your car based on your availability.

The price is very reasonable and it is market average price. They are so far the best shipping company as I also moved some bulk items and household appliances using their services. I have few bad experiences with other companies. This is my recommendation. Action speaks for itself.

Please PM me if you are interested as I know the person in-charge since I have used their services for a quite number of time. I can link you to them easily. Thanks. =)
