I have the same situation, when i bought my leaf,I had thought that i would save same money on it's service and gas, and than, I got that expenses are the same, off course its good for nature, but it's makes me disappointed a little bit :(
by the way, if you need to relocate your leaf its better to some carrier to ship it, cos as said upper it will be horrible trip, and if you need some help with it just ask and i'll do my best for you (cos i work in this business ;) )
I totally don't recommend you to do it, once i try some type of trips and it was really close to bad and so just rent a car, or if you have enough money you should think about buying a new car :)
