Need Tips on Buying a Car

My dream is to purchase a 70-72 Dart Swinger and have been searching the web for a few years to see what were available and the price. Most are not close to me, so a long distance transaction would have to occur.

How is the best way to pay for a car so that the seller and me the buyer would have a smooth transaction with neither concerned about getting taken? How is the best way to get the car transported to me?

Thanks for your responses in advance.
