+1 on flat towing; too easy to unbolt the driveshaft from the rear axle, just reach down through the battery box and you don't even have to get under the car.
If this is a recon mission (as opposed to towing an already road-worthy car), be certain that the wheels, tires, hubs, knock-offs, bearings and suspension are up to the task.
Frankly, if I HAD to tow it that far, I'd get all four (4) wheels off the ground and onto a trailer. There'd be A LOT less stress involved, for both you and the car.
