How do you go about buying a car on the other side of the country?

The last 5 cars I bought were all done online with me sitting on my *** many miles away from the US across the pond.
I only transfer money when I feel confident I'm actually getting a car in return.
Only once I had the feeling I took a too big risc when I bought a car but it all turned out good.
Shipping was in most cases handled by a shipper which could also arrange a title for the car for export if it didn't had one originally.
