I'm from Cambodia, I want to order buy the car. So where can I get the information. About the ship and tax price?

go online and look for shipping companies- there are several- you can also ask a classic car dealer near you- they ship regularly and they may be able to handle the transaction for you- unless you are buying a valuable classic, the shipping cost is probably prohibitive- while you are talking to the dealer in classics, in Cambodia, see what he has in stock- that would be the easy way to get a cool car
