Probably the only real way to have all the bases covered is to trailer it home.

IF something were to happen on the way home like an accident or something, that would not be the time to find out that something wasn't right. And if you have to go through multiple jurisdictions, who knows what little detail there could become a big issue.

The only other thing I can think of would be to have the vehicle assigned to the dealer and let them sell it to you so that they could issue you a 'drive away' permit if that state even has such a thing. We have them here in Illiniois just for this situation. BUT! Here in Illinois that would mean that the vehicle would be subject to sales tax unless the states are reciprocal.
