I've done it 3 times. I am also from Europe.
I call the seller and make a conversation. Normally I can tell if the seller is after my money or a honest guy.
The seller gives me his bank details and I make a wire transfer into his account. As soon the money is in he releases the car. I always have a shipping company who is arranging haulin from the sellers house to the docs.
Done this 3 weeks ago. Bought a 72 camaro from a very friendly seller in Arizona. I wired the money and a truck came by to pick up the car.
No worries. If the money is in your account everything is fine.
Maybe you can help the guy to bring the car to the docs (if you live close by)
The seller will ask you to make a bill of sale. sometimes lower than the sales price. this is to lower import duties. Does not affect you.
questions? just let me know.
