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

Being in Canada I have bought 2 cars for the US that were all over 1800 miles away. I bought when dollar was par or close to it.

I leveraged the members on this website to make the purchases. I asked for any local members willing to check out the car for me. People here are real helpful. Typically had 10 or more offers. Found someone in each case that was very qualified and mechanically savvy. I offer to pay them but they turn it down. So I ask for an address and I send them a little something for their time. Lots of dependable transport companies on here too. Both purchases went off perfectly.
