It is the shippers responsibility to make Customs aware of certain high tech gadgets that came with the car eg. navigational equipment or audio equipment that they may not notice. In certain situations where the whole car has been outfitted with expensive audio equipment the equipment should be taken out and shipped separately or the car and equipment should be shipped in a container. Less expensive equipment that you have installed in your auto such as cell phones with their speaker phone attachments should be taken out.

When you deliver your vehicle there should be less than a quarter tank of gas in the tank and your car should be in good shape and not leaking anything deemed hazardous. All cars leaking gas, motor oil, battery or radiator fluids will be deemed hazardous and will not be shipped. Extra gasoline canisters, cases of motor oil, cleaning and polishing solvents are deemed hazardous and can't be shipped with the car.
