1972 Dodge Dart 360 T/F-727 drives great $1,650.00

It has no problems, but anything could happen. I honestly thought about driving it down there and flying home, but I'd have to bring a buddy (or my father or wife) just in case and it would cost just as much as hauling it there and I would not be able to haul anything home on an airplane.

not sure how much airfare is, but if you could fly here and drive it home that would be the cheapest way to get it there. You could also wait it out on uship.com I have got lucky on there everytime I needed to ship something, although sometimes I've had to wait a long, long time and even then it's a scramble as shippers usually call me the day before when they can't get any other loads. This leaves you scrambling to get ahold of the seller to make sure he will be around. The good news is I am always around and the car is alwasy easy to get at.
I am willing to pick up the buyer at the airport to save wasting money on a cab.

I'll take the wheels off it and re-balance them as well. They didn't shake, but I haven't had it done so I'd feel better. The speed limits are only 55 here and I have ran it up to some good speeds, however I have never cruised at 80 mph for a couple hours stright like you can on the interstates. If I were driving it home I would just be mindful of the rpms as the 1:1 final drive in these mopars aren't exactly interstate cruising friendly. Although the rear gears are only like a 2.76:1 - 2.94:1 so it should do as good as any.
If I were you and I was driving it back that far I'd also change the fuel filter, air filter, plugs, plug wires, ditributor cap, distributor rotor, and thermostat when you're here before you leave. This may pay for itself by the time you made it home. I have lots of tools and could do it for you if you'd like. I could even get the parts at shop cost or bring your own. None of this would have to be done, but if it were me I'd like the peace of mind knowing it was done.
