Yea, I did a few months ago.
I would never buy a car cold though. I was fortunate that this one was only a few miles from my brothers place, so he checked it out for me. (car was in PA, I'm in CO)
Seems like alot of trouble for a road trip. Your not likely to make much of a profit on the deal till you figure in taxes, airline ticket, gas, hotel, etc. Plus the usual risk of buying a used car.
