A lot of people will tell you about the pitfalls in the process and there are many.
Assuming you are sure the car you want to buy is solid, these are the basic things you have to look after if you decide to go ahead:
- Sort out a secure payment method that protects you as well as the seller
- Arrange pickup and transport of the vehicle to port
- Sort out US Customs export paperwork
- Engage a shipping company/agent
- Engage a local Customs Broker in Australia
- Arrange local pickup and transport to home
There are plenty of people that will handle the entire process for you, but you will obviously be paying their margin on top of whatever the actual costs are and you are putting 100% trust in that person to do the right thing.
I've found the best mix of involvement vs. hassle for me is to look after the sale myself, then have a US shipping agent arrange the overland transport, export paperwork and shipping of the car to the Australian port. From there I use a local broker to handle the unpacking, Customs inspection and clearance of the vehicle. I then pick up the car myself and drive it home (only ever bought running/driving vehicles). That way I've got a sense of involvement and joy out of the process rather than just buying something online and having it delivered to my door.
Costs will vary a fair bit depending on the price of the car, where it's located in the US, the agent(s) you use and how much work you do yourself, but you can use the following as a very rough guide:
- Inland transport to US port: USD $500 - $1,500
- Shipping from Long Beach CA to MEL/SYD/BNE in shared container and all export paperwork preparation: USD $1,300 - $1,700
- Marine insurance (a must have) @1.5% of vehicle value
- Local broker's fees covering unpacking/inspection/clearance/etc: $1,500 - $2,000
- Local pickup and transport to home (if required): $300 - $500
- GST @10% on the landed value of the vehicle (purchase price + inland transport + shipping)
As an example, with a USD $30K car you could expect to be up for another USD $8K or so to cover all the associated transport and import/export costs to get it to your door, more if something goes wrong along the way.
I would never say don't do it, just be aware of the traps and make sure you add in the extra costs when you're looking at the shiny cars in the U.S. online listings
